 +
 +
== 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:
 +
# Stop the run.
 +
# Take the beam away, turn off SVT bias voltages, and wait 10 min.
 +
# Turn the bias voltages back on.
 +
# Check that the L0 bias currents have gone back down to ~4 uA
 +
# Bring back the beam and start a new run.
  
−
== Run Plan June 17 - 18, 2019 ==
+
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.

<!-- == Close the Hall at the beginning of the swing shift after everyone is out and MCC is ready to sweep == -->

== Harp Scan Procedure: ==

<!--* If after the sweep MCC is not ready to send a beam to Hall-B, keep the hall in control access for people still doing work on detectors.-->
 
  
−
== Establish beam to the tagger dump ==
+
# During harp scans, SVT must be retracted (motors/SVT Positioners). HVs on SVT, ECal and Hodoscope should be OFF.  
−
# See "General Instructions" on the right for details
+
# Halo counter FSDs (Downstream, HPS Up, and HPS Down) are masked, Beam current 50 nA, Orbit locks running.
−
# Log screenshots of the ECal and main HPS scaler screens for reference when the beam is established at the tagger
+
# Perform the HARP scan, log the results.
−
== Bring beam to FC ==
+
# If the beam looks different, you should call beam-line on-call that will advise on the next steps.
−
<!--# '''<font color=red> Important Note: Before bringing beams to FC, make sure that the SVT, Hodoscope, and ECal are off, SVT is fully retracted, the target is out. If this is a first time that beam goes to FC after machine settings have changed then the SVT protection collimator position relative to the beam trajectory is unknown and therefore HPS protection collimator must be retracted.</font>'''
+
# If the beam looks different, perform SVT wire scan, the target needs to be retracted as well for this one.
−
# '''Ask for 10 nA beam. When the beam sent to FC, it should be clearly visible on the downstream viewer. The halo counter rates downstream of the HPS, HPS-SC, and HPS-T should not be more than 10s of kHz. All upstream halo counters must be in the range of <100Hz.'''
+
<!--#* '''IMPORTANT, use the bottom SVT wire scan only.''' Top SVT wire is broken.-->
−
#'''First find the position of the collimator by performing the collimator wire scan. The current position of the wire for beam center is 4.41 (labeled on the GUI), if the measurement finds beam center at a different position use the expert GUI to set the 3.94 mm SVT collimator to the right position (current position is 6.212, which means that the distance between the wire and the center of the 3.94 mm hole is 1.802). After collimator is in place all beam studies should be done in these conditions with beam currents of 30 nA.''' -->

# ''' For SVT Operations:'''
−
<!-- ==[[SVT RECOVERY PROCDURES]]== -->
+
#* 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.

Latest revision as of 21:34, 4 November 2021


[edit]

HPS (E12-11-006) 2021 run, August - November 5
Beam energy 3.74 GeV
Important: Document all your work in the logbook!
Bluejeans for Run Meetings on DAY and DAY at 3 pm

RC: Maurik Holtrop, Thursday Nov 4 + Friday: Rafayel Paremuzyan

  • (757) 575-7540
  • 9 575 7540 from Counting Room
  • Personal cell: +1 (757) 753-7769

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].

* Energizing the chicane: Please read the "Turning Chicane ONN/OFF" document and ask if anything is not clear. When you pushe the ON button make sure current readbacks will behave as it is described in the scction III "Sequenc details"

* 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=1.14,Y=-2.9 and on 2H02(X=-2.5,Y=-1.1). Use the 2.82 mm SVT collimator

Before 9/9 this was: 2H00(X=0.3,Y=-1.) and on 2H02(X=-2.4,Y=-1.). Use the 2.82 mm SVT collimator

Run Plan Nov 1 - 5, 2021

  • Take a production data with hps2021_v2_3.trg trigger file. The beam current should be 120 nA, the target is 20 um W.
    • if the beam is down for less than 40 min for reasons that will not alter the beam trajectory to Hall-B, do not end the run instead pause DAQ: From the main hps GUI, open 'DAQ Status', click 'Pause Triggers' and confirm
    • Then retract the SVT to 3 mm, leave the bias voltages ON. After the beam is back and the halo and the detector rates look the same, bring the SVT to 0.5 mm and Resume DAQ: From the main hps GUI, open 'DAQ Status', click 'Resume Triggers' and confirm"
    • PLEASE close 'Are you sure want to pause trigger' and 'Are you sure want to Resume triggers' windows when you are done
  • Anytime MCC turns OFF or ON Hall-C, HPS SVT bias HV must be OFF, SVT retracted to 3 mm position. After the transition is complete, and the beam to Hall-B is established, perform a 2H02 harp scan at 100 nA and compare with previous scans. IF consistent (within a few 10s microns), precede with production running.


Hall Access Items (Wednesday, November 3rd):

  • Refill SVT chiller, check ECal and FEB chiller water levels, refill if needed - experts

Every Shift:

  1. Follow the 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 the 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 50 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.
    • Instructions on how to run SVT DAQ [2]

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.
    • Follow instructions under "Procedures" on the documentation tab for "Beamline"[3]. To tune the beam on tagger dump and perform harp scans beam current should be <10 nA.
    • Check the beam position on the tagger viewer, it should be approximately in the center of the screen, see https://logbooks.jlab.org/entry/3915622
    • Check X/Y positions on BPMs and harps and make sure they are close to the last known values.
    • Background levels on harp scans 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 4 hours or the configuration has changed, start with 8 mm
    • HPS target is OUT and Hodoscope and ECAL HVs are OFF
    • SVT is OUT (positions -1.8987 mm for top and -2,2025 for bottom 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 to the following corrector values: 2C22H, 2C23V, 2H00H, 2H00V, Compare them to ones that are in [4]. Make sure their values don't differ more than 100%. If there is such a 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 the beam spot is visible on Downstream Viewer.
    • If the MCC operator is not able to tune the beam for more than 15 minutes, then notify RC!
    • Follow the instructions under "Procedures" on the documentation tab for "Beamline"[5] 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), then gradually increase to 100 nA. For orbit lock position values see "Important instructions" section at top of the page . Use the 2.82 mm SVT collimator. (positions changed 10/3/21 by mg).
    • Tune beam profile at HPS using measured widths 2H02A harps. The required beam profile at 2H02A harp is: X-width <~0.1 mm, Y-width <~ 0.05 mm. Compare the beam profile measured with 2H02A harps with previous scans ([6],[7]).
    • 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 [8]
    • Positions on BPMs must be close to what they were before [9]
    • When everything is stable, perform SVT wire scan and compare with the nominal [10]
    • 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).
  2. Before accepting the 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.
