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:
−
# SVT Setting (call SVT expert in)
+
# Stop the run.
−
#* If beams are stable, SVT expert moves SVT to 1.0 and then 0.5 mm
+
# Take the beam away, turn off SVT bias voltages, and wait 10 min.
−
#* record occupancy, latency, data size, and deadtimes
+
# Turn the bias voltages back on.
−
# Record Data with 4um target
+
# Check that the L0 bias currents have gone back down to ~4 uA
−
#* Use v7_200nAtrig.
+
# Bring back the beam and start a new run.
−
#* Save scalers, trigger gui, FADC display gui each run.  
+
 
−
#* Be sure to follow General Guidelines, especially Every Shift and Every 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.
−
#* Do one 2H02 harp scan per shift;
+
 
−
#* Fill out BTA;
+
== Harp Scan Procedure: ==
−
#* Monitor and record BPM 2H02 history carefully to insure stable beams.  
+
 
−
#* If beams are not stable, get MCC to fix it!
+
# During harp scans, SVT must be retracted (motors/SVT Positioners). HVs on SVT, ECal and Hodoscope should be OFF.  
−
#* After each run execute this script (replace RunNb by the actual run number):
+
# Halo counter FSDs (Downstream, HPS Up and HPS Down) are masked, Beam current 100 nA, Orbit locks running.
−
#** <tt> hps2tape.sh RunNb</tt>
+
# Perform the HARP scan, log the results.
−
# Beam current scan (to be scheduled by RC)
+
# If the beam looks different, you should call beam-line on-call that will advise on the next steps.
−
#* Take data at various currents: 50nA, 100nA, 250nA, 300nA ...
+
# If the beam looks different, perform SVT wire scan, the target needs to be retracted as well for this one.
−
=== Miscellaneous Notes: ===
+
#* '''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.'''
 
# '''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.

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 September 8 - 9, 2019

  • Take production data with PROD66 (PROD67) / hps_v12_1.trg 20um target at 120 nA, HPS collimator 3.94 mm. Length of the run will be defined by the SVT bias currents, but no longer than 4 hours.
    • After run starts run the script "ben-trigger-structure.sh [CURRENT RUN NUMBER]" on any clonPCs and make sure pop-up graph shows continuous decanting distribution, does not have peaks (bumps). If peaks will show up, make a log entry with the graph.
  • After beam is OFF, 8:00 AM on Monday, do the following:
    • turn OFF detectors (SVT, hodoscope, ECal), and retract SVT
    • turn off the chicane
    • ask for a restricted access
    • start worming up SVT and FEBs
  • Calibration runs before run ends: - DONE!
    1. Random trigger run, 20 um W target, 120 nA beam current, trigger file "hps_v11_5_random_15kHz.trg" - 1x4 hour run
    2. Low luminosity run, 8 um target, 120 nA beam current, trigger "hps_v12_1.trg" - 2x4 hour runs
    3. SVT bias scan - 2 hours
    4. FEE run, 20 um target, 120 nA, trigger TBD (Nathan) - 1x2 hour run
    5. ??? Run with different SVT positions, 20 um target, 120 nA beam current, trigger "hps_v12_1.trg" - 8 hours
    6. Straight track run, setup with 2H02 wire, trigger "hps_v6_FEE_STRAIGHT.trg" - 1 hour, about 20M events

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, use the bottom SVT wire scan only. Top SVT wire is broken.

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).
  2. 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.
