Come to your shift in time for the shift change, 10-15 minutes before the start of your shift.

  • If it is your first shift or a shift after a long pause, do shadow an earlier shift for at least 4 hours to familiarize yourself with all shift duties and technicalities of the ongoing experiment.

Follow the Short Term Schedule

  • The RC must be notified before changing run conditions

Operate the Data Acquisition

Take action on and log alarms

At the end of the shift, submit the strip charts to the logbook

  • If they are not up already: (CS-Studio → Tools → Strip Charts → livePlot)
  • Right click within the grid, choose "Load a Configuration", select "Beamline4Logbook_visibleHaloCounters"
  • Choose a time-span width of 10 hours (right-click below x-axis)
  • To make a logbook entry:
- Right click within the grid of one of the charts, choose "Make Logbook Entry"
- The title of the logbook entry can be changed, eg to Strip charts
- Un-click ELOG, select HBLOG, and click on "Make Entry" to submit

Communicate with your co-shift person:

  • Remind them to read the tab 'Shift Worker'.
  • Discuss any issues with the shift worker before making extra logbook entries.
  • Remind the shift worker of the end-of-shift Checklist.
  • Use the CS-Studio Logbook entry tool for all screen shots (but the strip charts)!
  • Note that the Logbook Entry tool puts the entry in the HBRUN logbook by default. Other logbooks can be added or selected from the drop down menu.

Check for and read any comments to logbook entries made during your shift.

Keep your shift summary up to date in HBLOG. Record all significant happenings.

  • Refer to relevant logbook entries in the shift summary.
  • Include a run list for the shift with relevant run information.

Ensure that all monitoring plots and are logged and checked against the reference plots for every single run.

  • Both, you and the shift worker should run mon12 and reset & check spectra frequently.
  • If the worker shift is remote, maintain communication over Zoom.
  • If you have any other questions or uncertainties about what to do, call the RC.

The shift worker (if in person) should log the 'clas12online reconstruction plots at the end of a run. Running the program on more than one CH computer has been causing problems.

In case of RICH issues, check the RICH manual for the current guidance: https://github.com/JeffersonLab/clas12-manuals/blob/master/rich/Novice/RICH_Controls.pdf

New MVT LV Reboot Procedure can be found at tab 'GENERAL INFORMATION'.

Fill out BTA hourly;

  • Accelerator beam time (do not change these values):
    • ABU: acceptable beam used
    • BANU: beam acceptable but not used (should be reflected in our PCC and UED)
    • BNA: beam not acceptable (e.g., tuning, drifting, not focused)
    • ACC: Accelerator Configuration Change (e.g., pass change)
    • OFF: Accelerator is down
  • Experiment beam time (do change these values):
    • ER: Experiment ready (should be 60 minutes - PCC - UED)
    • PCC: Planned configuration change (when the beam is masked while radiators are moved, target change, DAQ (stopping/starting runs, tests, etc.)
    • UED: Unplanned experiment down (hardware failure, DAQ crashes, our problems, ...)
    • Exception: BANU, due to time spent on beam tuning and BPM checks after beam down, should be counted as ER on our side.
  • Enter fields at the "Shift Information" tab.
  • You must save at 7:00, 15:00, and 23:00, to send info to MCC. To see the save button, click 'edit all' or 'edit cc hours.'
  • Acknowledge the popup error message about the last hour not being completed by clicking OK.
  • Sign, viz log completed 8-hour sheet.
  • Note: we can change the time sheet up to 48 hours after completion.

Come to your shift in time for the shift change, 10-15 minutes before the start of your shift;

  • If it is your first shift or a shift after a long pause, do shadow an earlier shift for at least 4 hours to familiarize yourself with all shift duties and technicalities of the ongoing experiment.

Discuss any issue with the shift expert before making extra logbook entries; ask the shift expert to note the ongoing issue in the shift summary.

Use the CS-Studio Logbook entry tool for all screen shots (but the strip charts)!

Frequently

Reset and check mon12 histograms frequently, preferably each 1h

  • Note that some plots have radio buttons at the bottom to choose the sector. Remember to cycle through and check all sectors.

Once per run

Note that the CS-Studio Logbook Entry tool puts the entry in the HBRUN logbook by default. Other logbooks can be added or selected from the drop down menu.

Using the Logbook Entry tool, submit EPICS screenshots to the HBRUN logbook (one logbook entry) with beam ON

  1. Beamline overview (remote shift: in VNC or Web Browser)
  2. DAQ status
  3. CLAS12 trigger rates

Upload mon12 monitoring plots to the logbook with sufficient statistics and compare them to the reference and recent uploads (see Monitoring tab).

At the end of the run, submit the strip charts to the logbook

  • If they are not up already: (CS-Studio → Tools → Strip Charts → livePlot)
  • Right click within the grid, choose "Load a Configuration", select "Beamline4Logbook_visibleHaloCounters"
  • Choose a time-span width of 4 hours, compatible with the run duration (right-click below x-axis)
  • To make a logbook entry:
- Right click within the grid of one of the charts, choose "Make Logbook Entry"
- The title of the logbook entry can be changed, eg to Strip charts
- Un-click ELOG, select HBLOG, and click on "Make Entry" to submit

At the end of the run, upload the clas12online plots to the logbook.

  • The program can continue through a standard end/start of a run. However, after a DAQ restart, you must back out and restart clas12online.
  • If the DAQ has to be restarted, you can still make the upload before backing out.

Once per shift

Fill the shift checklist;

  • During production, get relevant values from the epics screens Beamline Overview, CLAS12 DAQ Status and CLAS12 Trigger;
  • During extended downtime, get relevant values from the latest EPICS screenshots that you made during production

- The shift worker should discuss an issue with the shift expert before making extra logbook entries.
- During production, not in extended downtime, the shift expert should ensure the shift worker is filling their end-of-shift Checklist when the beam is ON, not in the period of beam trips.
  • Check for and read any comments to log-book entries made during your shift.
  • Keep your shift summary up to date in HBLOG. Record all shift activities, issues, if any, and related communications with experts with details and/or reference to any associated logbook entries:
- Refer to relevant logbook entries in the shift summary.
- Include a list of runs taken during the shift with relevant run information;
- See, for instance, this shift summary where all relevant run info, links, and shift activities are cited.
  • Ensure that all MON12 monitoring plots are logged and checked against the reference plots for every single run; see the links under Monitoring tab;
- Both, you and the shift worker should run MON12 and reset & check spectra frequently.
  • If you have any other questions or uncertainties about what to do, call the RC.
  • MVT LV Reboot Procedure
    1. Turn LV OFF from MVT Overview->Low Voltage->MVT-All. LV status indicators should change from green to black;
    2. Wait 20 seconds, then turn LV back from the same menu;
    3. In the alarm handler, with a 2-minute alarm delay, there can be alarm NActiveCrates, status also reported on the MVT Overview GUI. This alarm will be cleared 2 min after LV is turned back ON;
    4. At this point, mvt1, mvt2, and mvt3 ROCS can be rebooted;
    5. Start a run by initializing DAQ from scratch: cancel-->reset-->configure-->download-->Prestart-->Go.
    6. If the beam is ON, and a reboot process takes more than 5 min, please call the DAQ and/or SVT/MVT/MM expert.
