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.
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) 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 “WC: Argon Flow” and “WC: Ethane Flow.”
Drift Chamber Gas Delivery Press (500 ± 5 Torr) Same as above. Record “WC: Ar:Eth Pressure.”
Drift Ch. Gas Isopropanol Temp. (2 ± 2 C) Same as above. Record the “Isopropanol Fridge” temperature.
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.
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.

HMS/SHMS/COIN Replays / Analysis up to date? 1. Ensure the online (50k) replays located in ROOTfiles/Analysis/50k/*<run-number>_50000.root have been completed and reviewed for current shift runs.
2. Ensure the offline (full) replays located in ROOTfiles/Analysis/<purpose>/*<run-number>_-1.root are at least in-progress.
Check the box if things are as-planned / current. See Analysis How-to for details.
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.
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.
