* '''Before leaving the hall and going to beam permit check that dome lights, forward carriage lights, and pie tower lights are OFF'''
 
* '''NEW:''' We have a new policy NOT to leave the beam viewer in the beam at all times, to avoid damage to electronics, cameras etc. Please REMOVE the beam viewer unless we are actively tuning the beam or calibrating beam position/raster.
 
*'''''NEW'': We have a new FSD condition that the raster is operating.'''
 
** IF there is any ammonia sample (NH3 and ND3) in the target, the raster '''MUST''' be operating at all times. The Raster FSD must be UNMASKED. Orbit locks MUST be OFF (except for brief moments to restore beam position).
 
** For beam tuning or other non-rastered beam, the Raster FSD must be MASKED.
 
* NOTE: It should no longer be necessary to quit RasterMon at the end of each run and restart after a successful "Go" for the next run, but if DAQ crashes, you SHOULD follow these steps, and the same for mon12. '''Make sure there is ONLY ONE INSTANCE of RasterMon AND mon12 running anywhere in the Counting House.'''
 
* REMINDER FOR ALL EXPERTS: Please take care to fill out the BTA carefully and correctly. The info from EPICS is not always correct, e.g. when taking data with low beam current, you should change the ABU to the proper (estimated) time by hand instead of simply accepting "0" if you are actually taking data.

* We should change the HWP ("lambda/2 plate"), after a full day of useful data on NH3 or ND3. WE MUST INFORM THE OTHER HALLS WHENEVER WE DO THAT
 
* We should reverse the target polarization after every TWO days of good data taking. So the sequence is "1 day on ammonia, swap HWP, one day on ammonia, flip target polarization, one day on ammonia, swap HWP, one day on ammonia".
 
* Moller runs should be taken with 10 nA.
 
* Do a RICH Recovery procedure only once a day during day shift (in between runs) if everything is okay. If a RICH problem occurs, you might have to do the RICH Recovery procedure also (see below).
 
* '''After each change of running conditions''' (target type, luminosity): Please check that the trigger alarms (on rate/nA) are set appropriately and change them as needed.

NOTES:
# Once beam is available, tune it on the tagger dump. Beam is currently setup for this already.
+
* Watch the beam positions (and thus the midstream halo counters) closely and ask MCC to adjust the positions if they are (on average) >=0.1mm off.
# Once upstream harp scans are acceptable (See below References and Standards), establish 4 nA beam on the FC. ** Get clean beam **
+
* Remember, the hall will only be dropped in controlled mode once someone goes downstairs and enters the hall. You/RadCon should do that right away after calling MCC.  
## (NOTE: the beam raster MUST be on at all times, hence you cannot do a harp scan at 2H01). You can temporarily put in the beam viewer to take a look at the profile, but then it has to be taken out. Some of the above is also described in the manuals - Physics-Quality Beam and Performing Møller Runs under “Shift Documentation” tab of the Run Group C run wiki.
 
# <b> We want to re-do the optimization for the raster settings. </b> Start a run and using both the new mon12 plots created by Raffa, and the FT asymmetry (mon12). Change the raster offset by -0.1 in X and Y and check that the amount of "red areas" are similar for all 6 sectors and no yellow or white, and the FT asymmetry is roughly 0. In the previous reference runs, the beam was too much to the right and too high. (Note that the target is large enough in diameter so that you shouldn’t hit the edge - confirm with your rastermon. Note that whenever you change the raster offset, you will have to observe how 2H01 x and y change, and tell MCC that those are the new values to shoot for. (You can tell them to stop trying to center the beam on 2H01 while you are trying out different offsets - otherwise you might end up working at cross-purpose).
 
# Note the final raster parameters and positions on 2H01 - update the whiteboard and th "Short-Term Schedule” accordingly, and inform MCC. <br /> You don’t need to start a new run for every new set of raster parameters - you can just clear mon12 and rastermon. Ideally someone should write down what you observe and log the raster DC occupancies and the FT asymmetry plots for each setting.
 
# Once the raster is satisfactory, start a long production run. We want at least 50M events.
 
# Depending on the report from the FT (Forward Tagger) analysis, we may go back to doing the 50nA "cold irradiation" process. Check the RC.
 
 
 
==== <font color=green> Cold Irradiation Process</font> ====
 
In this process we want to add the irradiation of the target by increasing the beam current. For this <font color="red"> <b>CLAS must be off </b></font>.<br />
 
<b>Procedure: </b>
 
* Turn off ALL high voltages, but put MVT in "safe" mode.
 
* Turn off the low voltage for the FTCal, FTHodo, FTT, etc. Any doubt then turn it off. If anything trips, leave it off.
 
* <font color=red><b> DO NOT Increase the raster size.</b></font> We do not want to fry the FTCal.
 
* Insert the FCup beam blocker.
 
* You have to allow MCC increase the Fast Shutdown levels to Midstream: 20000, Downstream: 2000000 (i.e. 10x what they are now.) Then ask for 50 nA beam, increasing "slowly" from 20 nA while you watch for FSD or high counts on the beam line monitors.
 
* Irradiate the target for about 2 hours actual beam time, with this high beam current and raster size. Actual 2hours will probably take 3 hours on the clock.
 
* Then we need to check whether the FT is still o.k. - for that, we need to take a regular run (4 nA and normal raster size) with full CLAS12 on, use the PROD66_pin configuration. Take 50M events, then repeat back to 50nA run.

'''Reference Monitoring Histograms'''
+
'''Counter rates'''
 +
* With 6 nA beam, the upstream counters should read zero.
 +
* The Midstream ones should read 0-20 Hz or so.
 +
* Greatly increased rates may indicate bad beam tune or bleed-through from other Halls.
  
'''Counter rates'''
+
= GENERAL INFORMATION =
* Upstream counters integrated rates: 0-15 Hz (acceptable up to 100 Hz are acceptable) @50 nA.
+
<!--####################################### GENERAL INFORMATION ########################################-->
* Midstream counters: 10-20 Hz (acceptable up to 50 Hz) @50 nA.  
+
 
* Counting rates of ~ hundreds of Hz may indicate bad beam tune or bleed-through from other Halls.
+
'''see below for Known Detector Issues'''
 +
 
 +
== General Information ==
 +
 
 +
* To open CS Studio interface, type "clascss" in some terminal.
 +
 
 +
* '''Controlled access''': after you call MCC, they will drop the hall to controlled access once someone goes down and calls them for entry. Then call when they should go back to beam permit and call again to say you want the beam back and what beam current. Rapid access is controlled access without RadCon.
 +
 
 +
* If MCC needs to '''diagnose beam with a harp''', we can offer them tagger 2C24 and follow the procedures required for that. '''2H01 harp scan should not be done when we have beam raster on.'''
 +
 
 +
* '''BMT''':
 +
** '''After HV trip''': the channel HV should be turned back on as soon as you notice the trip, power cycle by turning HV OFF and ON '''without waiting for any amount of time'''.
 +
** '''HV frequently tripping''': Call expert. Do not change HVs without approval from the expert.
 +
 
 +
* '''mon12''': It can happen that histograms do not get cleared completely at run start. This is seen eg as an excess of small multiplicities. The remedy is to quit mon12 and open it again. Other than that, small multiplicities come from time intervals with beam down. You might want to look at the multiplicities before uploading the mon12 histograms in the logbook.
 +
 
 +
* '''DAQ''':
 +
** rastermon should be using ET on clondaq6
 +
*** this means startup of rastermon via command line: rastermon --et --host clondaq6
 +
** It should no longer be necessary to quit RasterMon at the end of each run and restart after a successful "Go" for the next run. However, if DAQ crashes, you SHOULD follow these steps, and the same for mon12.
 +
 +
* '''Magnet trip''': call "Engineering on call", if due to cryo, also inform the target expert about the cryogenic issues.
 +
 
 +
* '''Holes in CND occupancies: CAMAC CFD crate was turned off/on for some reason. You need to run the script to set the thresholds for CND CFDs. Go on a clondaq machine and type cnd-cfd-thresh -w 0. Or call the CND phone if this doesn't work.
 +
 
 +
* '''Hall lights''': Before leaving the hall''' and going to beam permit check that dome lights, forward carriage lights, and pie tower lights are OFF.
 +
 
 +
* '''Moller runs''': should be taken with 8-10 nA.
 +
 
 +
* '''Beam viewer''': Please REMOVE the beam viewer unless we are actively tuning the beam or calibrating beam position/raster, to avoid damage to electronics, cameras etc.
 +
 
 +
* '''Change of running conditions'''
 +
** Check that the trigger alarms (on rate/nA) are set appropriately and RC changes them as needed.
 +
** Whenever the target type or polarization direction changes, or the half-wave plate status changes, make sure to enter a comment in the BEGIN RUN / END RUN comment box.
 +
** Do not change running conditions while a run is ongoing. This includes changing target polarization or HWP, etc.

# '''ECAL''': ECAL_HV_SEC2_WI_E36 is off as it does not hold voltage

Follow-up Re: RICH tile 21 in sector 1 is dead. Working without one tile out of 276 for a moment
# '''tdcecal6 and tdcecal1 rocs''': These rocs could show errors in the DAQ screen. If so, check roc-rates, trigger rates and monitoring plots. If all looks okay, continue data taking.

https://logbooks.jlab.org/entry/4079190
  
# The main lights in the Hall ('''dome lights''') and the Forward Carriage lights are being kept off because of light leaks affecting some of the detectors. If these lights are switched on during access, they should be switched off when leaving the Hall. Refer to these photos:
+
Tuesday, February 7, 2023:

BMT Sector 2 Layer 5 is broken (HV set to 200 V)
#* OFF: [https://logbooks.jlab.org/entry/3825731]
 
#* Note that the dome lights when switched off cannot be turned back on immediately because they require 10-15 min to cool down.
 
# In case of a '''Torus and/or Solenoid Fast Dump''' do the following:
 
#* Notify MCC to request beam OFF and to drop Hall B status to Power Permit
 
#* Call Engineering on-call and target expert
 
#* Make a separate log entry with copies to HBTORUS and HBSOLENOID logbooks. In the "Notify" field add Probir Goshal, Dave Kashy, and esr-users@jlab.org
 
#* Notify Run Coordinator
 
#* Turn off all detectors
 
# Observe the guidance of the alarm handler.

** Helicity Trigger Asymmetry strip-chart (CS-Studio -> DAQ -> Helicity-Latched Trigger GUI Screen -> click on "Menu" -> myaPlot (not accessible remotely) -> Choose "load config time axis: start: -12 hours end: NOW" and click "accept"
 +
*** [https://logbooks.jlab.org/entry/4123228 Example] 
 +
*** '''Choose reasonable y / x axis ranges:''' R-click on the axis -> Modify (axis-name) Axis
 +
*** For the y axis in the bottom panel, choose the NMR polarization and a reasonable range for the y axis (always from 0 to some maximum value), same for the 60-min trigger bit polarization. Those two do NOT have to have the same scale - it is better to try to get the dark blue and red curves to lie on top of each other (more or less).
 +
*** Set the time axis auto-update.  ">>" symbol will appear below the time axis when this is activated.  (Right-click on X axis ->" [A] Set Auto Time Stepping")

Run Coordinator and Target Expert Schedule

Longterm Run Plan

Medium-Term Run Plan (FTon Portion Part 2)

IMPORTANT SHIFT NOTES

* In case of medical or fire emergency, call 9-911 from a LANDLINE phone in the Counting House
* If you have symptoms or a positive COVID test, do NOT come to your shift - instead, inform the PDL and the RC and JLab medical services immediately so that replacements can be arranged.
* Remote shift: If needed, worker shifts can be taken from off-site. Inform the PDL and RC. Also, make sure that you follow the instructions under the "Worker Shift" Tab - you need some lead time to set up!
Note to shifts, please:
* read the logbook, be aware of previous 24 hours
* arrive at least 10 minutes early for shift change
* refresh the run wiki pages, look over them every shift:
** follow the expert/worker shift instructions 
** find latest pitfalls and known issues under GENERAL INFORMATION
* communicate with your co-shift person
** the shift expert should know about and refer to logbook entries in their shift summary
** the shift worker should discuss an issue with the shift expert before making extra logbook entries

Short Term Schedule for the Week from Wednesday, March 15th, to Monday March 20th, 2023

  • Current: 4 nA
  • Run duration: 100M events or 4 hours, whichever comes first.
  • Note, BOM is not installed for this experiment, so it does not matter whether it appears masked in FSD or not.
  • Conditions for raster operation:
    • IF there is any ammonia sample (NH3 and ND3) in the target, the raster MUST be operating at all times. The Raster FSD must be UNMASKED. Orbit locks MUST be OFF (except for brief moments to restore beam position).
    • For beam tuning or other non-rastered beam, the Raster FSD must be MASKED.
    • If MCC needs to diagnose beam with a harp, we can offer them tagger 2C24 and follow the procedures required for that. 2H01 harp scan should not be done when we have beam raster on.
    • Changing raster offset: ask MCC to NOT correct whatever happens on 2H01. Note new 2H01 values and inform MCC of the new 2H01 x and y values - then they can keep the beam at those positions.
  • Experiment setup is "FTon"
  • If HWP is changed, start a new run

PLAN for March 15-20, 2023

Note: an hour before changing the HWP, call Bill Henry (from Hall A) at 215-908-2245. He offered his help in optimizing the beam charge asymmetries when changing the HWP. He will stop by the counting house and run his code, which will take a minute. We will do the HWP changes during the day shifts.

  • Wednesday, March 15th: Beam study downtime starts at 8:00 AM. Beam is expected to be back by 15:00 PM. If they beam shows up before 22:00 PM, we will need to take a Moller run. Then, start taking data on ND3(+) (torus outbending, 4nA beam current, HWP IN).
  • Thursday, March 16th: Data taking on ND3 (+) (torus outbending, 4nA, HWP out)
  • Friday, March 17th: anneal the target and flip the polarization to negative. Will take about 3 hours starting around 9AM. Then, take data on ND3 (torus outbending, 4nA, HWP out)
  • Saturday, March 18th: Continue taking data on ND3(-) (torus outbending, 4nA, HWP IN)
  • Sunday, March 19th: Will change the target to C sometime in the day shift and start taking data. Will go to restricted access and will organize this between RadCon and Target Experts.
  • Till Monday, March 20th, 07:00 AM: Continue taking data till the beam goes away.
  • When the beam goes away:
  1. Turn all HV OFF except SVT and BMT. For FT we turn HV OFF, but keep the chiller and LV ON, Raffaella will do some LED calibrations.
  2. Solenoid will remain ON for the target group to do NMR studies.
  3. The torus should be ramped down. Morgan or Denny can do it if they are around at that time, or call Eugene and he do it.
  4. The hall should go to controlled access awaiting for radcon to come and do a full survey for restricted access.
NOTES: 
* Watch the beam positions (and thus the midstream halo counters) closely and ask MCC to adjust the positions if they are (on average) >=0.1mm off.
* Remember, the hall will only be dropped in controlled mode once someone goes downstairs and enters the hall. You/RadCon should do that right away after calling MCC. 

DAQ configuration

  • Configuration is currently PROD66/PROD66_PIN, trigger file rgc_300MeV_v1.4_no_DC.trg
  • NOTE: UNLESS a RICH problem crashes the DAQ, do NOT interrupt an otherwise smooth run to do a RICH recovery - instead do this in between runs.
  • NOTE: BOTH the shift expert AND the shift worker MUST check and reset monitoring histograms at least once every 30-60 minutes to make sure there are no major detector problems. Sometimes it is the only way to know that a roc needs to be rebooted. Watch the raster pattern!
  • At the end of each run, follow the STANDARD DAQ RESTART SEQUENCE:
    • "end run".
    • If the run ended correctly and you will run with the same configuration and trigger file, then: "prestart", "go"
    • If you are changing configuration (between PROD6X and PROD6X_PIN) or trigger file: "cancel", "reset", "configure", "download", "prestart", "go".
    • if the run did not end correctly or if any ROCs had to be rebooted:
      • Quit ALL running instances of mon12 and rastermon
      • "cancel", "reset"
      • "configure", "download", "prestart", "go"
      • restart mon12 and rastermon
  • After each step, make sure it is completed in the Run Control message window. If a ROC has crashed, find which one it is, issue a roc_reboot command ON JUST THAT ROC and try again. Contact the DAQ expert if there are any questions.

References and Standards

5-pass (10.55 GeV) Running conditions

  • Torus at 100% current, inbending electrons. Setpoint = +3770 A (Readback = +3766 A)
  • Solenoid set-point of 2416.4 A results in the read back 2419.23 A and exactly 5.00 T field on center

Raster settings (current as of February 9, 2023)

  • x: Vpp = 2.7 V, offset = 0.0
  • y: Vpp = 2.05 V, offset = 0.50 V
  • Fundamental Period = 2 s
  • The correct raster calibration constants should be automatically loaded by rastermon - if not, enter them through "Config" by hand:
  • f(x) = 0.0104*x + -25.5
  • f(y) = -0.0115*y + 24.4

Nominal Beam Positions (current as of February 9, 2023)

  • 2C21A, X = -0.4 mm, Y = +0.6 mm
  • 2C24A, X = -2.0 mm, Y = +0.6 mm
  • 2H01, X = -1.0 mm, Y = +0.9 mm
  • Orbit lock on 2C24 and 2H01 ONLY if raster is OFF, otherwise orbit lock on 2C21 and 2C24 (note: this appears as "stopped" on the beam line GUI).

FSD Thresholds

  • Upstream: 2000 Hz
  • Midstream: 2000 Hz
  • Downstream: 100000 Hz (1e5)
  • BOM: 1000000 Hz (BOM not installed for RG-C)
  • 5 ms dwell time

Reference plots and histograms

Counter rates

  • With 6 nA beam, the upstream counters should read zero.
  • The Midstream ones should read 0-20 Hz or so.
  • Greatly increased rates may indicate bad beam tune or bleed-through from other Halls.

see below for Known Detector Issues

General Information

  • To open CS Studio interface, type "clascss" in some terminal.
  • Controlled access: after you call MCC, they will drop the hall to controlled access once someone goes down and calls them for entry. Then call when they should go back to beam permit and call again to say you want the beam back and what beam current. Rapid access is controlled access without RadCon.
  • If MCC needs to diagnose beam with a harp, we can offer them tagger 2C24 and follow the procedures required for that. 2H01 harp scan should not be done when we have beam raster on.
  • BMT:
    • After HV trip: the channel HV should be turned back on as soon as you notice the trip, power cycle by turning HV OFF and ON without waiting for any amount of time.
    • HV frequently tripping: Call expert. Do not change HVs without approval from the expert.
  • mon12: It can happen that histograms do not get cleared completely at run start. This is seen eg as an excess of small multiplicities. The remedy is to quit mon12 and open it again. Other than that, small multiplicities come from time intervals with beam down. You might want to look at the multiplicities before uploading the mon12 histograms in the logbook.
  • DAQ:
    • rastermon should be using ET on clondaq6
      • this means startup of rastermon via command line: rastermon --et --host clondaq6
    • It should no longer be necessary to quit RasterMon at the end of each run and restart after a successful "Go" for the next run. However, if DAQ crashes, you SHOULD follow these steps, and the same for mon12.
  • Magnet trip: call "Engineering on call", if due to cryo, also inform the target expert about the cryogenic issues.
  • Holes in CND occupancies: CAMAC CFD crate was turned off/on for some reason. You need to run the script to set the thresholds for CND CFDs. Go on a clondaq machine and type cnd-cfd-thresh -w 0. Or call the CND phone if this doesn't work.
  • Hall lights: Before leaving the hall and going to beam permit check that dome lights, forward carriage lights, and pie tower lights are OFF.
  • Moller runs: should be taken with 8-10 nA.
  • Beam viewer: Please REMOVE the beam viewer unless we are actively tuning the beam or calibrating beam position/raster, to avoid damage to electronics, cameras etc.
  • Change of running conditions
    • Check that the trigger alarms (on rate/nA) are set appropriately and RC changes them as needed.
    • Whenever the target type or polarization direction changes, or the half-wave plate status changes, make sure to enter a comment in the BEGIN RUN / END RUN comment box.
    • Do not change running conditions while a run is ongoing. This includes changing target polarization or HWP, etc.

Known Issues

FTT alarms - can be ignored (we do not have the FTT installed)

Fr 11 Nov 2022 ECAL PMT_SEC2_WO8 HV is disabled https://logbooks.jlab.org/entry/4080950

Follow-up Re: RICH tile 21 in sector 1 is dead. Working without one tile out of 276 for a moment https://logbooks.jlab.org/entry/4079453

Run #17396: RICH lost three scalars https://logbooks.jlab.org/entry/4079190

Tuesday, February 7, 2023: BMT Sector 2 Layer 5 is broken (HV set to 200 V)

Shift expert tasks

  • Come to your shift in time for the shift change, 10-15 minutes before the start of your shift.
  • Follow the Short Term Schedule as outlined by RC
    • Run Plan, DAQ Configuration, and References and Standards
    • also check tab GENERAL INFORMATION
  • Keep shift summary up to date in HBLOG. Record all that happens.
  • Polarized target:
    • Helicity-Latched Trigger GUI and the Helicity Trigger Asymmetry strip-chart (not accessible remotely) (example https://logbooks.jlab.org/entry/4041939). (ONLY WHILE ACTUALLY RUNNING ON NH3 AND ND3 targets!)
    • In case of any issues, contact the polarized target expert on call.
    • Ice on the run valve
    • NMR running (ONLY WHILE ACTUALLY RUNNING ON NH3 AND ND3 targets!)
      • The JLab Polarization Display is seen via a VNC window in the counting room. Here, the NMR Controls' blue bar must be moving, indicating that the NMR is running and the polarization is measured.
      • If the NMR display is frozen or disappears, here are the steps to follow:
        • Open a new terminal window on the bottom right-most screen.
        • Type "ssh clasrun@clonsl1"
        • Type "nmr-vnc”
        • Click "Run" under "NMR Controls" - the window should now be updating (blue bar moving)
      • The NMR frequency needs to be controlled by hand. If you see target polarization (on the red graph) starting to drop, call the expert. They will guide you through the adjustment procedure. This will be in the electronics room by the door to the counting room, in the third crate from the right ("CR-6"). White box which says "EIO Tube" and has a red button at the top right, which says "Move", next to a display for "Position". This will be the one to press, under guidance of the target expert.
    • Alarms from System RG-C Polarized Target (alarm handler).
  • Do a RICH recovery (press the RICH Recovery button on the GUI) once daily during day shift, between runs. Please log in shift summary.
    • Note the automated "RICH Recovery" sequence already confirms RICH4 is up and accepting ssh connections before claiming success.
    • You have to "Cancel->Reset->Configure->Download->Prestart" before starting the next run.
  • Fill out BTA hourly. Click "Load from EPICS" to automatically fill the left side then correct as needed.
    • Accelerator beam time:
      • ABU: acceptable beam used (eg harp scans, calibrations, trigger settings, running)
        • The info from EPICS is not always correct, e.g. when taking data with low beam current, you should change the ABU to the proper (estimated) time by hand instead of simply accepting "0" if you are actually taking data.
      • BANU: beam acceptable but not used (eg radiator change or our problems)
      • BNA: beam not acceptable (eg tuning, drifting, not focused)
    • Experiment beam time
      • ER: experiment ready
      • PCC: planned configuration change (when beam is masked while radiators are moved, DAQ (stopping/starting runs, tests, ...) are PCC..
      • UED: unplanned experiment down, is used for hardware failure
    • Enter fields at tab "Shift Information"
    • Promptly send "Info for MCC" at 7:00, 15:00, and 23:00
    • Sign, viz log completed 8 hour sheet


In case of other questions or uncertainties of what to do, call the RC or PDL

(remote) shift worker: see dedicated Worker Shift tab above.

Shift Worker Tasks

  • Check the information in the Short Term Schedule and GENERAL INFORMATION, for every shift
  • Come to your shift in time for the shift change, 10-15 minutes before the start of your shift.
  • Use the new HBRUN logbook for automated and run-specific entries and screenshots, see https://logbooks.jlab.org/entry/4048698


Make the following log entries ONCE per run

  • Screenshots: submit to logbook only if you capture the information with beam ON
    • Beamline Overview, in VNC or Web Browser
    • CLAS12 Trigger rates and DAQ status
    • RGC Polarized Target GUI - under Beamline on CS-Studio
    • Helicity Asymmetry Strip Charts - see [10] for an example. Also read and follow the instructions below under "Log the Strip Charts".
  • Upload monitoring plots to logbook
    • Standard spectra (mon12): inspect all monitoring histograms ' and carefully compare them to the corresponding reference histograms: reference, current, and 5 most recent runs, see link under tab Useful Links
      • You can choose a different reference run if you are confident what you are doing, the reference numbers refer to logbook entries.
    • Raster Monitoring (use "Log Entry" button on RasterMon screen at bottom-right corner).
      • An example of a "decent looking" RasterMon is here: [11]. The x and y distributions should show a smooth dome, without any horns or spikes on it and without the distributions being cut off at the edges.

Once per shift:

  • Fill the shift checklist
  • Log screen shots of RICH temperature and scaler maps. Log in RICH logbook.

Regularly:

  • reset & check spectra frequently (every 30 - 60 minutes)
    • Some plots in the online mon12 have a choice of histogram sets per sector, select buttons at the bottom of the plot. That means you have to look at all sectors for these histograms.
    • The logbook entry shows all histograms.
  • Check the life cam of the polarized target run valve for plumes or ice buildup (hallbcam04)
    • Make sure you refresh the web page! Its no longer necessary to put a snapshot into the logbook UNLESS something looks suspicious. In THAT case, immediately inform the target expert(s).
  • Log the strip charts in time intervals according to the x-axis time span, via right-click on the screen and selecting "Make Elog Entry". Make sure NOT to submit to ELOG.
    • Beam current and position strip-charts (CS-Studio -> Beamline -> Strip Charts)
    • Helicity Trigger Asymmetry strip-chart (CS-Studio -> DAQ -> Helicity-Latched Trigger GUI Screen -> click on "Menu" -> myaPlot (not accessible remotely) -> Choose "load config time axis: start: -12 hours end: NOW" and click "accept"
      • Example
      • Choose reasonable y / x axis ranges: R-click on the axis -> Modify (axis-name) Axis
      • For the y axis in the bottom panel, choose the NMR polarization and a reasonable range for the y axis (always from 0 to some maximum value), same for the 60-min trigger bit polarization. Those two do NOT have to have the same scale - it is better to try to get the dark blue and red curves to lie on top of each other (more or less).
      • Set the time axis auto-update. ">>" symbol will appear below the time axis when this is activated. (Right-click on X axis ->" [A] Set Auto Time Stepping")

For REMOTE Shifts (offsite):

ATTENTION: If you plan to take (a) remote shift(s), you MUST test your setup (including VNC connection) at least 24 hours before your first shift!
