# <b> Note: in order to have reliable readings on two important for HPS BPMs, 2H00 and 2H02, beam current should be >25 nA. Before moving forward with 2H02A harp scans and beam profile tune, make sure orbit lock is engaged at positions on 2H00(X=0.00,Y=0.00) and on 2H02(X=-1.00,Y=-0.85).
+
# <font color=red> Important Note: Before bringing beams to the FC, be sure that the SVT and ECal are off, the SVT fully retracted, the target out,  and the 2.82 mm SVT collimator is in. All beam studies should be done with beam currents between 25 nA and 30 nA and all detectors OFF and SVT fully retracted.</font></b>
+
# The required beam profile at 2H02A harp is: X-width <~0.25 mm, Y-width <~ 0.10 mm, and the tilt angle <15 degrees. The spot on the Chromax viewer should be close to x=-2mm, y=-5mm. <b> Do not waste too much time on the initial beam tune, as long as rates on the halo counters are low - Downstream L/R/T/B and HPS-L/R <~few Hz/nA, and HP-SC < few x 10 Hz, the following program still can be done:</b>
+
# Set beam position
+
#* Have MCC move beam to standard values (see "General instructions" on the right)
+
#* Perform a SVT wire scan
+
#* Ask for the beam to be moved up by 100um at 2H02
+
#* Repeat and record 2H02 harp scan, SVT wire scan and BPM values.
+
#* Scan of the 2.82 mm collimator and re-center it. Record the new position have it entered into the epics data base.See https://logbooks.jlab.org/entry/3379405
+
# Restore ECal and Trigger
+
#* Turn on ECal
+
#* Record FADC rates with and without the 4 um target at 200 nA. Agree with last weekend? See https://logbooks.jlab.org/entry/3379417
+
#* Trigger/DAQ expert checks trigger rates, DAQ, and deadtime with 200 nA beam on 4 um target. Record:

#*# ''trigger rate gui''  (requires DAQ Prestarted with <tt>HPS/Run2016/v7_200nA.trg</tt>)
+
# SVT Setting (call SVT expert in)
+
#* If beams are stable, SVT expert moves SVT to 1.0 and then 0.5 mm
+
#* record occupancy, latency, data size, and deadtimes
+
# Record Data with 4um target
+
#* Use v7_200nAtrig.
+
#* Save scalers, trigger gui, FADC display gui each run.
+
#* Be sure to follow General Guidelines, especially Every Shift and Every Run.
+
#* Do one 2H02 harp scan per shift;
+
#* Fill out BTA;
+
#* Monitor and record BPM 2H02 history carefully to insure stable beams.
+
#* If beams are not stable, get MCC to fix it!
+
#* After each run execute this script (replace RunNb by the actual run number):
+
#** ssh hpsrun@clondaq5 
+
#** > hps2tape.sh RunNb
+
# Beam current scan (to be scheduled by RC)
+
#* Take data at various currents: 50nA, 100nA, 250nA, 300nA ...

** Moeller run: Trigger file '''hps2021_v2_2_moller_LowLumi.trg''', Beam current '''50 nA''', Target '''8 um''', 200 M events.
 +
* '''Take production data''':  120 nA beam on the 20 um W target, PROD77 configuration, production trigger '''hps2021_v2_3.trg'''. Each run should last about 4 hours.
 +
* '''Setup production data taking''':  Start 50 nA beam on the 8 um W target, PROD77 configuration, production trigger '''hps_1.9_v2_3.trg'''. Turn ON detectors, bring SVT in to 0.5 mm. Start the run and check occupancies. Increase the beam current (up to 100 nA) until you reach occupancies of ~1.5% for L0t and L0b. End run and start a new one.
 +
* We will try to have the beam on FCup. with 8 mm collimator in place, <font color=red> No Halo FSD should be masked at this step. </font>
 +
** If the beam passes through successfully, then we should ask the beam to be off, and put the 2.88 mm collimator, and do 2H02, SVT top and bottom scans to make sure beam position and profile are good.
 +
* Start a Moeller run 'hps_1.9_Moller_v2_6.trg' for 4 hours, if statistics will be less than 300M, take another run with Moeller trigger.
 +
* '''Take production data''': Beam current 70 nA, target 8 um W. Each run should last about 4 hours. Trigger hps_1.9_v2_6.trg. -->
 +
* Take one hour Empty target run, with the same current, and the same trigger file.
 +
* 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: <font color=red> From the main hps GUI, open 'DAQ Status', click 'Pause Triggers' and confirm </font>
 +
** 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: <font color=red> From the main hps GUI, open 'DAQ Status', click 'Resume Triggers' and confirm" </font>
 +
** <font color=red> PLEASE close 'Are you sure want to pause trigger' and 'Are you sure want to Resume triggers' windows when you are done </font>
 +
* 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.

<!-- ===At 8 am on Friday, October 2, beam will be OFF for the pass change. Hall-B goes back to the 2nd-pass, Hall-A takes the 1st-pass=== -->
  
==<font color=blue><b>General Instructions:</b></font>==
 
=== Locking up the hall on Fridays ===
 
* At 2pm check the status of the activities in the hall and notify RC if there are potential delays for the lockup at 3pm.
 
* Work with the hall work coordinator (Doug Tilles or his designee) to make sure hall is ready for sweep at around 3pm: vacuum is good, magnet power supplies are turned ON and on remote, LCW is on.
 
* Make sure experts, beamline, ECal, SVT, and slow controls, checked their systems befor the lockup.
 
* When ready notify MCC to start seep and lockup of the hall.
 
* Make sure all necessary monitoring GUIs are up and running.
 
* Make sure beam viewer screens are up.
 
  
===Acceptable Beam Conditions:===
+
===Hall Access Items (Wednesday, October 20):===
# <b> To establish good beam conditions: </b>
+
* Refill SVT chiller, check ECal and FEB chiller water levels, refill if needed - experts
#* <font color='red'><b>Make sure SVT is retracted and completely OFF and ECal is OFF as well </b></font>
+
#* First send beam to the tagger dump (ask MCC to turn ON the tagger magnet). <!-- meanwhile turn on the Chicane (see above) -->
+
#* Check that beam type is "Photon" on the BTA GUI (can be opened from "Beam" GUI).
+
#* Check the beam position on the tagger viewer, it should be approximately in the centre of the screen
+
#* Follow instructions under "Procedures" on the documentation tab for "Beamline"[https://wiki.jlab.org/hps-run/images/e/e6/HPS_beamline_comm.pdf]. To tune the beam on tagger dump and perform harp scans beam current should be <10 nA.
+
#* Check profile using 2C21 and tagger harp scans, and compare the positions and widths with previous scans ([https://logbooks.jlab.org/entry/3376192],[https://logbooks.jlab.org/entry/3376194]). Positions on both harps should be with +/- 1mm, widths on 2C21 should be <~0.1+/-0.05 mm, and on the tagger harp (2C24) <~0.35 +/- 0.1mm.
+
#* 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!-->
+
# <b> Before sending beam to the Faraday cup</b>
+
#* <b> Check that SVT protection collimator is ON </b>
+
#* HPS target is OUT
+
#* SVT is OUT (position 0 mm) and voltages are OFF
+
#* ECal HV is OFF
+
# <b> Send beam to the Faraday cup</b>
+
#* Follow the instructions under "Procedures" on the documentation tab for "Beamline"[https://wiki.jlab.org/hps-run/images/e/e6/HPS_beamline_comm.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 >25 nA</b>. All studies should be done with beam currents between 25 nA and 30 nA.
+
#* Ask MCC to establish 25 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=0.00,Y=0.00) and on 2H02(X=-1.00,Y=-0.85). Use the 2.82 mm SVT collimator. </font></b>.
+
#* Tune beam profile at HPS using measured widths on 2H02A harp. The required beam profile at 2H02A harp is: X-width <~0.25 mm, Y-width <~ 0.10 mm for commissioning, and Y-width ,~ 0.05 for physics running, and the tilt angle <15 degrees.
+
#* 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 should count less than Hz/nA and 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 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/3376894]
+
#* Insert the 4um W target without turning off the beam.
+
#<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>
+
  
===<font color=red>Recovering from beam trips when running SVT at 0.5 mm:</font>===
+
<!--
# SVT HV will trip off automatically
+
* Investigate noise in ECal top - Nathan/Ben (4 hours)
# Check the FSD GUI to see if high rates in the HPS halo counters generated the trip
+
* Replace/relocate the camera on the SVT chiller - Nathan (30 min)
#* If it was not an HPS halo counter trip, MCC will restore the beam as usual (following their own instructions). As soon beam is back and stable, restore SVT HV.
+
* Calibration runs before run ends: - DONE!
#* If it was an HPS halo counter trip, MCC will not restore the beam. Inform MCC that we will get back to them when we are ready for beam.

===Setting up Chicane for E=2.3 GeV:===
+
== SVT Bias Currents: ==
'''Note:'''  This requires Beam Permit and NO beam to HPS / Faraday Cup. 
+
# Turn on chicane power supplies following instructions on the documentation page on [https://wiki.jlab.org/hps-run/images/c/c6/Chicane_settings.pdf]
+
  
 +
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.
 +
 +
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: ==
 +
 +
# 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 50 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.
 +
#* 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 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.
 +
<!--
 +
#* Check profile using 2C21 and tagger (2C24) harp scans and compare the positions and widths with previous scans ([https://logbooks.jlab.org/entry/3899869],[https://logbooks.jlab.org/entry/3899819])
 +
#** 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 scans 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 beamline 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 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 [https://logbooks.jlab.org/entry/3903361]. Make sure their values don't differ more than 100%. If there is such a 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 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"[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>, then gradually increase to 100 nA. For orbit lock position values see "Important instructions" section at top of the page <!-- on <font color=red>2H00(X=0.3,Y=-1.) and on 2H02(X=-2.7,Y=-0.90)-->. Use the 2.82 mm SVT collimator. (positions changed 10/3/21 by mg)</font></b>.
 +
#* 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 ([https://logbooks.jlab.org/entry/3696650],[https://logbooks.jlab.org/entry/3903891]).
 +
#* 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 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.'''

[edit]

HPS (E12-11-006) 2021 run, August - October'
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: 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=-1.2). 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 October 25 - 27, 2021

  • Take one hour Empty target run, with the same current, and the same trigger file.
  • 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, October 20):

  • 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)</font>.
    • 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).
  1. 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.
