Direct link to the Hall C Shift Checklist
  • The How-to page is extremely helpful. Use Firefox's "Page search" to help find what you are looking for.
  • There is also an older Shift Checklist help file, which may help to locate items. (But it is a stale document.) Below is an updated table.
  • Please contact Mark Mathison (mathison@jlab.org) for any updates or corrections that should be made to this table.
What Where to find it How to do it
Your Name Name of person(s) filling out the checklist
Beam Conditions from Overview Screen, DAQ, MEDMs, and Scalers
Beam Energy (MeV) The Hall C Summary Screen should be displayed on a wall monitor. If not see this page to bring it up: EPICS/Accelerator_Screens. Write down the Hall C beam energy
Beam Current (uA) Same as above MPS and Hall C BCM readings should be similar. Record the reading
Beam position lock on? Use jmenu and search for 'lock.' Then choose 'Orbit Locks Normal View and look for 'HallCOrb.' It should be in green and show 'Running.' Green color corresponds to the 'lock' on state. Grey color means 'lock' is off.
Beam energy lock on? Use jmenu and search for 'lock.' Then choose 'Energy Locks.' '0R, 1A, 2A.' should all be green. This indicates the locks are ON. (NOTE: During Sept 2020 running, 2A is OFF and replaced by a PID lock 'OPSPID09'. Watch the HALLC:p stripchart on the Wall monitor for drifts instead, particularly if Hall A is OFF.)
IPM3H07A, B, and C BPM positions. Are they nominal? See the Hall C Summary Screen. Alternatively open the jmenu and search for myaplots. Open MyaPlot (OPS). Input 'IPM3H07A.XPOS' in the search field (use mouse middle click for paste action). Repeat plots for 'IPM3H07A.YPOS','IPM3H07B.XPOS','IPM3H07B.YPOS', 'IPM3H07C.XPOS' and 'IPM3H07C.YPOS'. Click on each plot line to obtain corresponding beam position value. Tip: use ↑ and ↓ arrows to change X axis scale; use ← and → arrows to move along X axis. Record the displayed beam position. Compare it with the nominal position posted on the white board or sticky note.
Fast Raster Pattern Go to the electronics room and verify the raster pattern on the oscilloscope screen is square. If beam is on and raster is NOT square, stop beam immediately.
Fast Raster Setpoint for Width, Height (x, y) [mm] Use jmenu and search for 'fast raster.' The screen is "Hall C Fast Raster." Record the set sizes in the “Set Raster Size” box.
Fast Raster Measured Currents (IxO3H, Ix04H, Iy03V, IyO4V) [A] Use jmenu and search for 'fast raster.' The screen is "Hall C Fast Raster." Record the the four measured currents (Ix and Iy for two H and two V coils) from the “Raster Measured Current” box.
Helicity Reporting Delay (No Delay, ___ Windows) Use jmenu and search for 'helicity,' then choose 'Helicity Control.' Look for 'Reporting Delay.' Record the time of delay (it should be 8 windows).
Alarm Handler Status (General) The Alarm Handler process must be running and always visible on one of the desktop machines. If it isn't, bring it up using this page: Hall_C_Alarm_Handler Verify that it is running, and that the alarm sound is NOT silenced. (N.B.: this is not the old legacy high-voltage alarm. )
HMS Collimator Setting Use jmenu → 'Standalone Menus' → 'Hall C.' On the Hall C Operations Menu under “Experiment Specific” is HMS Coll. Motion Control. Determine and record the collimator position. For physics runs, HMS should be either Small or Large Collimator.
SHMS Collimator Setting Use jmenu → 'Standalone Menus' → 'Hall C.' On the Hall C Operations Menu under “Experiment Specific” is SHMS Coll. Motion Control. Determine and record the collimator position. For physics runs, SHMS should be Collimator.
Target in use Ask the target operator (TO). Record which target is in the beam.
Drift Ch. Mixer Flows: Ar/Eth (~0.3/~0.3 slpm) Normally, From terminal, run go_gasFlow; If remote monitoring isn't functional, and we have to manually check gas flow out in the gas shed.' See this hclog entry for instructions.
Drift Chamber Gas Delivery Press (500 ± 5 Torr) Same as above. Record “pressure.”
Drift Ch. Gas Isopropanol Temp. (2 ± 2 C) Same as above. For now, record 2 C if the isopropanol is bubbling when you go out to check the gas shed. (Normally, Record the “Isopropanol Temp (C)” temperature, aka "hc_gasshed_temp_ethanol". If a nonphysical value is displayed, re-run the go_gasFlow command.)
HMS Drift Chamber Threshold (5.5V?) Run jmenu and search for 'threshold', and select the 'HallC Drift Chamber Thresholds' item. Record the HMS 'Read' value.
SHMS Drift Chamber Threshold (4.5V?) Run jmenu and search for 'threshold', and select the 'HallC Drift Chamber Thresholds' item. Record the SHMS 'Read' value.
Gas System Interlock Panel Go to the electronics room and locate the panel in rack CH03B10, next to the BCMs. Record "Gas on" if the LED indicator on the panel is illuminated, record "Gas off" if not.
SHMS NGC gas mix (% neon) Type “go_munin” in Terminal and select “gas_shed” under Categories on the left side of the page. You can also find the needed charts here: [Flow and Temperature Charts] Record “NGC Neon Fraction” (FALL 2022: XEM2 is running at a 75:25 mix. The fraction should be about 25%)
SHMS NGC gas flows (Ne / Ar) [slm] Type “go_munin” in Terminal and select “gas_shed” under Categories on the left side of the page. You can also find the needed charts here: [Flow and Temperature Charts] Record “NGC Neon Flow” and “NGC Argon Flow.” (FALL 2022: XEM2 is running at a 75:25 mix. The ratio of the flows should match!)
HMS Angle (TV/GUI) Type “go_cameras” to bring up a TV image of the angle scale on the floor (see link here: Hall_C_Cameras). The Rotation GUI can be executed from "go_magnets." (see link here: Spectrometer_Rotation Note only one copy of the magnet control screen can be up. So make sure one isn't already up.) Read the angles and write it down. There is a slight offset between the TV and GUI values (the TV is the most accurate one).
SHMS Angle (TV/GUI) Same as above. Read the angles and write it down. There is a slight offset between the TV and GUI values (the TV is the most accurate one).
Hall Survey (TV Cameras) Scan all the cameras in the hall looking for anything unusual. Verify that you performed the inspection by checking off the box.
HMS & SHMS Doors Closed? (TV) Note this while doing hall survey with TV cameras. ALL shield house doors should be closed when taking beam. Check HMS door with HCCAM04 (yellow). Check SHMS door with HCCAM01 (orange).
Hall TV Cameras returned HOME? Return TV cameras to HOME positions. Note: cameras may be left in a different position if there is a specific need. Check the box to indicate that cameras were returned to desired positions.
HMS Shutter (Magnet GUI) Open/Closed status is indicated on the "Magnets" GUI on the far right of the HMS magnets menu bar. Alternate method: Use TV camera on HMS side of the hall to inspect the indicator light on the control box outside the HMS shield house door. Shutter must be OPEN when taking data in the HMS.
SHMS Shutter (Magnet GUI) Open/Closed status is indicated on the “Magnets” GUI on the far right of the SHMS magnets menu bar. Alternate method: pan the HCCAM04 (SHMS bubblers) camera to the small mirror on the left; if you can see the bolts on the vacuum flange, the shutter is open. If the shutter is installed it must be “OPEN” when taking data in the SHMS. If the Noble Gas Cerenkov is in use then the shutter is not installed; in this case write “NA” on the checklist.
Unser (3H05) Temperatures OK (110 ± 1 F) Go to the electronics room, and locate the top of rack CH03B11, LED digits. Nominal 110 degrees. Record the reading.
BCM (3H04) Temperatures OK (110 ± 1 F) (Camera) Locate Rack HC01Z01 in the experimental hall using the cameras. Use this link for help: Hall_C_BCM_Temperatures. Record the reading.
NPS Detector Temperatures OK Temperature strip charts should already be pulled up, they are usually on desktop 2 on the High Voltage/Strip Charts monitors. If they are not, open a new LivePlot, right-click in the window and select "Load a Configuration". Select the directory "yaopeng", and open the "nps_temp_1.xml" file. Repeat for the other 7 files in this directory (8 LivePlot windows total). Verify that temperatures are in an appropriate range (~10 to 25 degrees C).
NPS Chiller Status Refer to Phoebus GUI by running "./phoebus-4.6.10-SNAPSHOT/phoebus.sh". From the main menu, click on "Chillers" to bring up the chillers menu. Note that only one copy of Phoebus can be up, so make sure one isn't already up. Phoebus is usually running on desktop 1 of the NPS monitors. Use this link for help: NPS_Calo_SlowControls Verify that for both the crystal and electronics zones, the readout temperature is between the set limits, pressure readouts are acceptable, and that there are no alarms. As of 12/2/23, temperatures should be between 15 and 30 degrees in both zones, the crystal zone pressure is ~37 psi, the electronics zone pressure is ~60 psi. Alarms should be green.
NPS Chiller Readback Temperatures Active? Temperature strip charts should already be pulled up. If they are not, find them as described above. Find the variables hcnps_intlk_chiller_CZ_read_chiller_temp and hcnps_intlk_chiller_EZ_read_chiller_temp (usually located in the bottom right of the screen). Confirm that these plots are actively reading out and not flatlining.
NPS Detector LV Refer to Phoebus GUI by running "./phoebus-4.6.10-SNAPSHOT/phoebus.sh". From the main menu, click on "NPS LV" to bring up the LV menu. Verify that LV for cards 0 and 1 are on. Card 2 is currently off as of 12/2/23. On/off buttons may flash with a purple border, and some current readouts may have a red border, this is normal.
NPS Detector HV Refer to Phoebus GUI by running "./phoebus-4.6.10-SNAPSHOT/phoebus.sh". From the main menu, click on "Overview" to bring up the HV menu. Verify that all channels are on which should be on. As of 12/2/23, columns 0 through 8 are turned off, with the exception of a couple channels in columns 0 and 5. There are plans in the next few days to do more work on the calorimeter, so this may change. All channels in column 30 should be off, UNLESS you are taking cosmics data, in which case, only two channels in that column should be on, the rest off.
NPS DC Current Anode If not running already, ssh to cdaq@cdaql3, cd ~/yaopeng/monitoring, and run ./run_nps_current_gui.csh. Verify that the GUI is running and updating periodically, and that the current does not exceed 30uA for any given channel. Hit rate gui is run as ./run_nps_cal_gui.csh
HMS Detector HV Refer to the HMS HV GUI from running "go_hv," if it isn't already up on a computer (it usually is!) Verify that GUI is “RUNNING” and not indicating any ’OFF’ or bad channels
SHMS Detector HV Refer to the SHMS HV GUI from running "go_hv," if it isn't already up on a computer (it usually is!) Verify that GUI is “RUNNING” and not indicating any ’OFF’ or bad channels.
HMS Momentum Set (+/- GeV/c) and Particle Charge (E or P) The HMS magnets Momentum setpoint (P0) and particle polarity (E or P) are displayed on the magnet controls screen. Use the screens available from the "go_magnets" command. Click on "Status" located on the top left of the header bar to view the HMS Overview. Write down P0 and either E for electron or P for proton. If GUI shows Using NonStandard Tune you must verify that the magnet Set Currents match the momentum specified in the Run Coordinator’s Run-Plan.
HMS Q1,2,3 and D Current Setpoints: ± setpoint Use the screens available from the “go_magnets” command. Click on "Status" located on the top left of the header bar to view the HMS Overview.

NPS Sweeper Magnet Locate sweeper magnet GUI, which should already be pulled up on one of the monitors. If it isn't, use jmenu and search for "NPS Combo". The screen is "Hall C NPS Combo". The same information can also be found from the Hall C Summary screen. From the sweeper magnet GUI, verify whether the magnet is on or off. Magnet should be on for production, off for elastic calibration.
NPS NDX Level Locate NPS radiation monitor strip charts, which should already be pulled up on one of the monitors. If they aren't, open a new LivePlot, right-click in the window and select "Load a Configuration". Select the directory "NPS" and open the file "NPS_RadMonitor". From the NPS radiation monitor strip charts, record the 4 NDX levels (INX3sH1_nDsRt for Neutron / INX3sH2_nDsRt for neutron / INX3sH1_gDsRt for gamma / INX3sH2_gDsRt for gamma)
SHMS Momentum Set (+/- GeV/c) and Particle Charge (E or P) The SHMS magnets Momentum setpoint (P0) and particle polarity (E or P) are displayed on the magnet controls screen. Write down P0 and either E for electron or P for proton. If GUI shows Using NonStandard Tune you must verify that the magnet Set Currents match the momentum specified in the Run Coordinator’s Run-Plan.
SHMS HB, Q1, Q2, Q3 and D Current Setpoints: ± setpoint Use the screens available from the “go_magnets” command. The magnet Set Currents, with sign, are on the individual PSU screens. Write down the Set Current polarities and values. (±xxxx.xx Amps)
SHMS HB, Q1, Q2, Q3, D N2/He Level [%] (50 to 75%) Use the screens available from the “go_magnets” command. Record He and N2 levels from their respective screens.
HMS Chamber fiducial efficiency (online analysis) [%] (Enter value; ideally > 95%) For the NPS experiment, this value is located in the report files for the 50k replays. SSH to cdaq@cdaql#. Run go_analysis_nps. Then cd REPORT_OUTPUT/COIN/. Then run grep "E SING FID TRACK EFFIC" [FileName], replacing [FileName] with the name of a recent report file. If the HMS is receiving electrons (normal production), the efficiency will be listed under "E SING FID TRACK EFFIC"; if it's receiving hadrons (elastic calibration), it will be listed under "HADRON SING FID TRACK EFFIC". See this log entry for an example. Record the appropriate efficiency value for the run
SHMS Chamber fiducial efficiency (online analysis) [%] (Enter value; ideally > 95%) This should be listed in the shift worker section of the report file from the most recent full run replay Record the appropriate efficiency value for the run
HMS Hodoscope Threshold Voltage Readback [mV] Now in Alarm Handler -- no manual check required.
SHMS/HMS/COIN CODA run numbers On the CODA GUI Screen. Record the current run number, or "--" if not running.
SHMS/HMS/COIN DAQ Trigger Rate [Hz] On the CODA GUI Screen, next to the appropriate prescaler value (ps1 thru ps6). Record the typical instantaneous rate
HMS/SHMS/COIN DAQ Livetime On the CODA GUI Screen, Use stripchart on the "Live Time" to estimate this value (beam ON!) Hall_C_DAQ#Live_Time_Display -OR- click on the report file attachement s/hms_replay_production_default_XXXXX_-1.report for a recent hclog analysis plots entry and look in the 'Shift Checklist Information' section at the top of the file.
HMS/SHMS/COIN Replays / Analysis up to date? Ensure the online (50k) replays located in ROOTfiles/COIN/PRODUCTION/nps_hms_coin_<run_number>_50k_events.root have been completed and reviewed for current shift runs. Check the box if things are as-planned / current. See NPS Online analysis (Fall 2023) for details. For the NPS experiment, shift crew is only responsible for online (50k) replays.
EDTM event count from last full run This should be listed in the shift worker section of the report file from the most recent full run replay. Quickly output EDTM info with command: grep 'EDTM' REPORT_OUTPUT/Analysis/<purpose>/Pion_replay_coin_production_XXXXX_-1.report, where XXXXX corresponds to the run number. It should be on the order of 40000 accepted EDTM triggers for a 1 hour run
HMS/SHMS "All (named) scaler channels are counting in go_xscalers_S/HMS?" Locate go_xscalers_HMS and go_xscalers_SHMS. All channels with proper names should be counting. Channels labeled like '12/6', '12/7', etc are spares. Unused h/pTRIG channels may also be zero. Find and CLOSE any extra xscaler GUIs when you are done.
HMS/SHMS S1x, h1x, 3/4 singles rates can be found in the same xscalers GUI Locate go_xscalers_HMS and go_xscalers_SHMS. HMS: h1x=s1x on HMS screen, 3/4=ptrig3. SHMS: s1x=s1x on SHMS screen, 3/4=ptrig1. Find and CLOSE any extra xscaler GUIs when you are done.
NPS EDTM Rate [Hz] Run "go_edtm get". Record the outputted EDTM rate.
HCLog screen shot of Target This should be done periodically by the TO. Make sure the TO has posted a screenshot of the target and relevant charts to the logbook
HCLog screen shot of Magnet screens (HMS+SHMS) Locate the magnet screens (should already be up on a computer) Take a screenshot (go to terminal and type "hclog" to make a log post, click "add attachment," then click the desired image) to include the rotation GUI and current settings/field readback. Make sure you have all of the PSU GUIs showing the set points. This usually takes 2/3 screenshots total.
HCLog screen shot of Temperature screens (NPS) Locate NPS temperature strip charts (should already be pulled up) Take screenshots of all the temperature charts and post to a logbook entry. This usually takes about 3 screenshots total. See this logbook entry as an example: https://logbooks.jlab.org/entry/4186864
