We will be running with 1.05GeV beam. This beam needs to be carefully restored, first to the tagger dump, then to the alcove and Faraday cup screen. See detailed instructions in the right pannel.
+
== SVT Bias Currents: ==
  
=== Short term schedule: ===
+
Shifters must pay attention to the L0 bias currents. This is on both the SVT motor GUI and the main bias GUI. The bias currents will slowly creep up over the course of a run. When the bias current is between 15-20 uA for either L0 sensor, do the following:
# <b>Turn ON the ECal</b> and check for normal scalers ([https://logbooks.jlab.org/entry/3334812])
+
# Stop the run.
# Call SVT expert. Expert will check conditions and <b>turn ON the SVT</b> <font color=red>Only SVT expert should move the SVT!</font>
+
# Take the beam away, turn off SVT bias voltages, and wait 10 min.
# <b> Take data at 40 nA for few hours</b>
+
# Turn the bias voltages back on.
#* Check if DAQ runs properly and if all monitors look reasonable on both SVT and ECal (call experts)
+
# Check that the L0 bias currents have gone back down to ~4 uA
#* Log errors for each DAQ crash
+
# Bring back the beam and start a new run.
#* Use HpsTrigCommV1M1.trg trigger file
+
# <b> Take trigger commissioning data runs</b>. See [[Media:HPS_TriggerCommissioning_March2015.pdf|Valery's note]] on the run Wiki under commissioning trigger.
+
# If orbit locks are on, call Rafayel for <b> beam trip study</b>. Take 4 hours of beam trip data with wire up; take 4 hours of beam trip data with wire down.
+
# In absence of other requests, <b> take data at 40 nA</b>. Be sure to block Faraday cup if higher current.
+
  
=== Miscellaneous Notes: ===
+
Do not let the bias current exceed 20 uA. It takes about 4-5 hours for the bias currents to creep up to those values. Call SVT expert if unsure.
  
# <b> If you change beam current current, turn orbit locks off first, there is a current - position dependence on the stripline BPMs 2H00 and 2H02 </b>
+
== Harp Scan Procedure: ==
# Do NOT change magnet currents when beam is on
+
# Do not run more than 30 minutes above 50 nA without the beam blocker put beam blocker in for long running at high current
+
  
 +
# During harp scans, SVT must be retracted (motors/SVT Positioners). HVs on SVT, ECal and Hodoscope should be OFF.
 +
# Halo counter FSDs (Downstream, HPS Up and HPS Down) are masked, Beam current 100 nA, Orbit locks running.
 +
# Perform the HARP scan, log the results.
 +
# If the beam looks different, you should call beam-line on-call that will advise on the next steps.
 +
# If the beam looks different, perform SVT wire scan, the target needs to be retracted as well for this one.
 +
<!--#* '''IMPORTANT, use the bottom SVT wire scan only.''' Top SVT wire is broken.-->
 +
 +
=== Important Notes: ===
 +
# When re-establishing beam to Hall B after a >1h long downtime follow "General Guidelines" on the right and the Beamline Procedures and Manual on the shift documentation page. Do not hesitate to call the beamline expert.
 +
# '''Do not run more than 60 minutes above 30 nA without the beam blocker in front of Faraday cup. Put beam blocker in for long running at high currents.'''
 +
# ''' For SVT Operations:'''
 +
#* From the time beam first comes into the hall until it is being delivered to the Faraday cup with orbit locks on for a known good trajectory, the SVT should be completely off. This is especially important during tuning to the tagger dump, when mis-steering of the beam can result in very high hard neutron backgrounds.
 +
#*Once stable beam is being delivered to the Faraday cup with orbit locks on for a known good trajectory, and the SVT collimator is in position, the FEBs and hybrids can be powered and operated, but the HV bias for the sensors must remain off.
 +
#*In order to turn on the HV, the FSD system must be functioning so a beam excursion that hits the collimator will quickly trip off the beam.

 +
===Establishing Physics Quality Beam for HPS:===
 +
# <font color='red'>'''Make sure SVT is retracted and detectors, SVT, Hodoscope and ECAL are OFF.'''</font>
 +
# <b>If the beam was off for 4 hours or more or in case of troublesome beam tuning, send a beam to the tagger dump:</b>
 +
#* Check that beam type is set to "Photon" (<tt>HPS_EPICS->Beam->BTA</tt>).
 +
#* Position "Blank" on the beam for the Hall-B collimator 
 +
#* Ask MCC to turn ON the tagger magnet and then deliver <10 nA beam to the tagger dump.
 +
#* Check the beam position on the tagger viewer, it should be approximately in the center of the screen
 +
#* Follow instructions under "Procedures" on the documentation tab for "Beamline"[https://wiki.jlab.org/hps-run/images/1/1e/HPS_beam_estab.pdf]. To tune the beam on tagger dump and perform harp scans beam current should be <10 nA.
 +
#* Check profile using 2C21 and tagger (2C24) harp scans and compare the positions and widths with previous scans ([https://logbooks.jlab.org/entry/3720088],[https://logbooks.jlab.org/entry/3720089])
 +
#** Positions on both harps should be within 1mm
 +
#** Width on 2C21 should be <~0.2+/-0.05 mm
 +
#** Width on tagger harp (2C24) <~0.5 +/- 0.1mm
 +
#* Background levels on harp scan are comparable to those of previous scans.
 +
<!--#* Halo counters UPS-L/R and TAG-L/T/T2 should be ~few Hz/nA [https://logbooks.jlab.org/entry/3376736]-->
 +
<!-- # <b> While MCC degausses the tagger magnet, verify that chicane is ON</b>
 +
#* If not, turn it on.  Strictly follow the procedure in the beam line manual!-->
 +
# ''' Before sending a beam to the Faraday cup '''
 +
#* If HPS chicane must be ON, make sure that chicane GUI says "Chicane Ready"
 +
#* Set Hall-B Collimator to 20 mm.
 +
#* ''' Check that SVT protection collimator is ON THE BEAM (2.82 mm). If the beam was off for more than 4HPS hours or the configuration has changed, start with 3.94 mm'''
 +
#* HPS target is '''OUT''' and Hodoscope and ECAL HVs are '''OFF'''
 +
#* SVT is OUT (position=0.000 mm on the main HPS scaler GUI) and bias HV is off (all red/green indicators RED in SVT bias GUI)
 +
#* If any uncertainty, page the experts
 +
#* Pay attention into following corrector values: 2C22H, 2C23V, 2H00H, 2H00V, Compare them to ones that are in [https://logbooks.jlab.org/entry/3689166]. Make sure their values don't differ more than 100%. If there is such difference, tell MCC about this.
 +
# ''' Send beam to the Faraday cup '''
 +
#* If the beam optics is correct, then you should immediately see the beam spot on the Downstream Viewer and on the 2H00 and 2H02 BPMS.
 +
#* If you don't see it immediately, and rates on halo counters are more than 100 Khz, then ask MCC, to change to pulsed (tune mode) beam, and ask to restore corrector values. At this point don't accept any CW beam, until beam spot is visible on Downstream Viewer.
 +
#* If MCC operator is not able to tune the beam more than 15 minutes, then notify RC!
 +
#* Follow the instructions under "Procedures" on the documentation tab for "Beamline"[https://wiki.jlab.org/hps-run/images/1/1e/HPS_beam_estab.pdf] to establish beam to the electron dump.
 +
<b> Note: in order to have reliable readings on two important for HPS BPMs, 2H00 and 2H02, beam current should be >30 nA.</b>
 +
#* Ask MCC to establish 30 nA beam with <font color=red>HPS</font> orbit locks on (We need '''HallBHPSOrb''' not '''HallBOrb''' configuration). <b>For orbit lock positions on <font color=red>2H00(X=1.0,Y=1.5) and on 2H02(X=-1.7,Y=0.3). Use the 2.82 mm SVT collimator. (positions changed 6/25/19 by mg)</font></b>.
 +
#* Tune beam profile at HPS using measured widths on 2H01A and 2H02A harps. The required beam profile at 2H02A harp is: X-width <~0.1 mm, Y-width <~ 0.05 mm. Beam profile using 2H01A and 2H02A harps with previous scans ([https://logbooks.jlab.org/entry/3696650],[https://logbooks.jlab.org/entry/3720218]) to compare.
 +
#* Check and log the beam spot on chromax viewer
 +
#* The halo counter rates before HPS must be very low:
 +
#*# Upstream Left and Right, and the tagger counters few 10's of Hz,
 +
#*# Downstream counters should count <Hz/nA
 +
#*# The halo counter rates on HPS, HPS-L/R/T/SC, depends on the collimator and HPS chicane settings, but should not be more than 50 Hz/nA [https://logbooks.jlab.org/entry/3696813]
 +
#* Positions on BPMs must be close to what they were before [https://logbooks.jlab.org/entry/3696813]
 +
#* When everything is stable, perform SVT wire scan and compare with the nominal [https://logbooks.jlab.org/entry/3720219]
 +
#* Once all the above is achieved, turn ECAL and Hodoscope HV '''ON''' to monitor and log ECal rates
 +
#* Insert the 20 um W target (turn beam off first).
 +
# '''Before accepting beam, make sure all the previous conditions are met. Always read previous log entries, compare settings of BPMs and correctors with previous settings using scaler_hps GUI.'''

#* If it was an HPS halo counter trip, MCC will not restore the beam until we request it. Inform MCC that we will get back to them when we are ready for beam.
 +
#*# Retract the SVT to its 1.5 mm stations, both top and bottom.
 +
#*# Tell MCC we are ready for the beam.
 +
#*# Once the beam is restored, confirm that both 2H02 beam positions x and y are as desired and halo counter rates are as expected.
 +
#*# Once the beam is stable for ~1 minute, restore SVT HV and the SVT to its nominal position.
 +
#*# Resume data taking.

===Acceptable Beam Conditions:===
 
  
# <b> To establish good beam conditions first send beam to the tagger dump (ask MCC to turn ON the tagger).</b>
 
## Check position, it should corresponds to previous good settings [https://logbooks.jlab.org/entry/3334787]
 
## Check profile using 2C21 and tagger harp scans, it should correspond to previous settings ([https://logbooks.jlab.org/entry/3334749],[https://logbooks.jlab.org/entry/3334751])
 
## Beam can be accepted at this level if it is within 20% of previous standards
 
## Halo counters TAG-L/T/T2 should be ~10Hz/nA [https://logbooks.jlab.org/entry/3326723],
 
# <b> While MCC degausses the tagger magnet, turn the chicane ON</b>
 
#* Strictly follow the procedure in the beam line manual!
 
# <b> Before sending beam to the Faraday cup</b>
 
#* Check 3mm collimator is IN
 
#* Check HPS target is OUT
 
#* Check SVT is out (position 0 mm)
 
# <b> Send beam to the Faraday cup</b>
 
#* Tune beam profile with 2H02A harp scan to be wide in X-direction and narrow in Y (see ref [https://logbooks.jlab.org/entry/3334783])
 
#* Check the beam spot on chromax viewer
 
#* The halo counter rates before HPS must be low:
 
#*# UPS-L and UPS-R few Hz/nA,
 
#*# The tagger counters and downstream counters should count  <<1 Hz/nA
 
#*# The halo counter rates on HPS, HPS-L/R/T/SC, depends on the collimator and HPS chicane settings, but should not be more than 100 Hz/nA [https://logbooks.jlab.org/entry/3328991]
 
#* Positions on BPMs must be close to what they were before [https://logbooks.jlab.org/entry/3334787]
 
#* Contact SVT expert to do SVT Wire Scan
 
#* Ask MCC to establish HPS orbit locks
 
#* Ask beam to be turned OFF to insert the 4um W target
 
#<b>Before accepting beam, make sure all the previous conditions are met. Always read previous log entries, compare settings of BPMs and correctors with previous settings using scaler_hps GUI. </b>

[edit]

HPS (E12-11-006) 2019 run, June X to August Y'
Beam energy 4.5 GeV
Important: Document all your work in the logbook!
Bluejeans for Run Meetings on DAY and DAY at 2pm

RC: Stepan Stepanyan

  • (757) 575-7540
  • 9 575 7540 from Counting Room

PDL: Valery Kubarovsky

  • (757) 876-1789
  • 9 876-1789 from Counting Room

Important instructions

* Turn OFF beam before target move!

* No access to the alcove if the chicane magnet beacon is ON.

Chicane magnets must be OFF if the hall is in Controlled access and access to the alcove is needed or when the hall is in Restricted access. If Chicane magnets are OFF, they can be energized only when the hall is in Power or Beam Permit, [1].

* TURN OFF the chicane magnet if beam is not available due to a thunderstorm. Loss off power would seriously damage detectors.

* Fill out BTA hourly. Click "Load from EPICS" to fill the left side, then make sure numbers are correct. If needed edit the entry.

NO ABUs or BANU if beam tune is in progress, make it all BNA with ER 100%. At the end of the shift save BTA to the logbook!

* Please close any GUI that is not being used, e.g. close harp scanner after harp scan is done, close chicane, after chicane is ON, etc.

* For orbit lock positions on 2H00(X=-0.5,Y=1.5) and on 2H02(X=-1.55,Y=-0.4). Use the 2.82 mm SVT collimator

am profile check once a day, at 9 am, using 2H02 and SVT wire harps

Run Plan August 23 - 30, 2021

  • Beam commissioning
  • ECal and Hof=doscope commissioning
  • SVT commissioning
  • Setting up Trigger and DAQ

Every Shift:

  1. Follow run plan as outlined by RC
  2. With any issue contact On-Call Experts or RC
  3. Monitor carefully the SVT bias current (see below for details)
  4. If any concern about beam stability, ask MCC if orbit locks are on (they should be ON).
  5. Keep shift summary up to date in HBLOG. Record all that happens.
    • Document any beam condition change and send scaler GUIs to HBLOG
    • Fill out BTA hourly. Click "Load from EPICS" to automatically fill the left side then make sure numbers are correct. If needed edit the entry. Note: in the "Sift information" tab choose experiment E12-11-006. . At the end of the shift send BTA to teh logbook.
    • Fill and submit the shift checklist in the logbook

Every Run:

  1. After "Go": Check SVT Occupancy
  2. Update the Run Spreadsheet
  3. Log screenshots of:
    • main scaler_hps display
    • ECAL FADC rate gui
    • Trigger rate gui
    • SVT and HODOSCOPE and ECAL Monitoring pdfs
  4. Please watch Hybrid sync gui for correct status (currently three red lights) and the L0-3 and L4-6 occupancy plots for any empty plots beyond the expected three.

SVT Bias Currents:

Shifters must pay attention to the L0 bias currents. This is on both the SVT motor GUI and the main bias GUI. The bias currents will slowly creep up over the course of a run. When the bias current is between 15-20 uA for either L0 sensor, do the following:

  1. Stop the run.
  2. Take the beam away, turn off SVT bias voltages, and wait 10 min.
  3. Turn the bias voltages back on.
  4. Check that the L0 bias currents have gone back down to ~4 uA
  5. Bring back the beam and start a new run.

Do not let the bias current exceed 20 uA. It takes about 4-5 hours for the bias currents to creep up to those values. Call SVT expert if unsure.

Harp Scan Procedure:

  1. During harp scans, SVT must be retracted (motors/SVT Positioners). HVs on SVT, ECal and Hodoscope should be OFF.
  2. Halo counter FSDs (Downstream, HPS Up and HPS Down) are masked, Beam current 100 nA, Orbit locks running.
  3. Perform the HARP scan, log the results.
  4. If the beam looks different, you should call beam-line on-call that will advise on the next steps.
  5. If the beam looks different, perform SVT wire scan, the target needs to be retracted as well for this one.

Important Notes:

  1. When re-establishing beam to Hall B after a >1h long downtime follow "General Guidelines" on the right and the Beamline Procedures and Manual on the shift documentation page. Do not hesitate to call the beamline expert.
  2. Do not run more than 60 minutes above 30 nA without the beam blocker in front of Faraday cup. Put beam blocker in for long running at high currents.
  3. For SVT Operations:
    • From the time beam first comes into the hall until it is being delivered to the Faraday cup with orbit locks on for a known good trajectory, the SVT should be completely off. This is especially important during tuning to the tagger dump, when mis-steering of the beam can result in very high hard neutron backgrounds.
    • Once stable beam is being delivered to the Faraday cup with orbit locks on for a known good trajectory, and the SVT collimator is in position, the FEBs and hybrids can be powered and operated, but the HV bias for the sensors must remain off.
    • In order to turn on the HV, the FSD system must be functioning so a beam excursion that hits the collimator will quickly trip off the beam.

General Instructions

Establishing Physics Quality Beam for HPS:

  1. Make sure SVT is retracted and detectors, SVT, Hodoscope and ECAL are OFF.
  2. If the beam was off for 4 hours or more or in case of troublesome beam tuning, send a beam to the tagger dump:
    • Check that beam type is set to "Photon" (HPS_EPICS->Beam->BTA).
    • Position "Blank" on the beam for the Hall-B collimator
    • Ask MCC to turn ON the tagger magnet and then deliver <10 nA beam to the tagger dump.
    • Check the beam position on the tagger viewer, it should be approximately in the center of the screen
    • Follow instructions under "Procedures" on the documentation tab for "Beamline"[2]. To tune the beam on tagger dump and perform harp scans beam current should be <10 nA.
    • Check profile using 2C21 and tagger (2C24) harp scans and compare the positions and widths with previous scans ([3],[4])
      • Positions on both harps should be within 1mm
      • Width on 2C21 should be <~0.2+/-0.05 mm
      • Width on tagger harp (2C24) <~0.5 +/- 0.1mm
    • Background levels on harp scan are comparable to those of previous scans.
  3. Before sending a beam to the Faraday cup
    • If HPS chicane must be ON, make sure that chicane GUI says "Chicane Ready"
    • Set Hall-B Collimator to 20 mm.
    • Check that SVT protection collimator is ON THE BEAM (2.82 mm). If the beam was off for more than 4HPS hours or the configuration has changed, start with 3.94 mm
    • HPS target is OUT and Hodoscope and ECAL HVs are OFF
    • SVT is OUT (position=0.000 mm on the main HPS scaler GUI) and bias HV is off (all red/green indicators RED in SVT bias GUI)
    • If any uncertainty, page the experts
    • Pay attention into following corrector values: 2C22H, 2C23V, 2H00H, 2H00V, Compare them to ones that are in [5]. Make sure their values don't differ more than 100%. If there is such difference, tell MCC about this.
  4. Send beam to the Faraday cup
    • If the beam optics is correct, then you should immediately see the beam spot on the Downstream Viewer and on the 2H00 and 2H02 BPMS.
    • If you don't see it immediately, and rates on halo counters are more than 100 Khz, then ask MCC, to change to pulsed (tune mode) beam, and ask to restore corrector values. At this point don't accept any CW beam, until beam spot is visible on Downstream Viewer.
    • If MCC operator is not able to tune the beam more than 15 minutes, then notify RC!
    • Follow the instructions under "Procedures" on the documentation tab for "Beamline"[6] to establish beam to the electron dump.

Note: in order to have reliable readings on two important for HPS BPMs, 2H00 and 2H02, beam current should be >30 nA.

    • Ask MCC to establish 30 nA beam with HPS orbit locks on (We need HallBHPSOrb not HallBOrb configuration). For orbit lock positions on 2H00(X=1.0,Y=1.5) and on 2H02(X=-1.7,Y=0.3). Use the 2.82 mm SVT collimator. (positions changed 6/25/19 by mg).
    • Tune beam profile at HPS using measured widths on 2H01A and 2H02A harps. The required beam profile at 2H02A harp is: X-width <~0.1 mm, Y-width <~ 0.05 mm. Beam profile using 2H01A and 2H02A harps with previous scans ([7],[8]) to compare.
    • Check and log the beam spot on chromax viewer
    • The halo counter rates before HPS must be very low:
      1. Upstream Left and Right, and the tagger counters few 10's of Hz,
      2. Downstream counters should count <Hz/nA
      3. The halo counter rates on HPS, HPS-L/R/T/SC, depends on the collimator and HPS chicane settings, but should not be more than 50 Hz/nA [9]
    • Positions on BPMs must be close to what they were before [10]
    • When everything is stable, perform SVT wire scan and compare with the nominal [11]
    • Once all the above is achieved, turn ECAL and Hodoscope HV ON to monitor and log ECal rates
    • Insert the 20 um W target (turn beam off first).
  1. Before accepting beam, make sure all the previous conditions are met. Always read previous log entries, compare settings of BPMs and correctors with previous settings using scaler_hps GUI.
