Important Shift Notes
- In case of medical or fire emergency, call 9-911 from a LANDLINE phone in the Counting House
- If you have symptoms or a positive COVID test, do NOT come to your shift - instead, inform the PDL and the RC and JLab medical services immediately so that replacements can be arranged.
- Read the logbook and be aware of previous 24 hours
- Arrive at least 10 minutes early for shift change
- Refresh the run wiki pages, look over them every shift.
- Follow the expert/worker shift instructions at the tabs above.
- Communicate with your co-shift person!
- The shift expert should know about and refer to logbook entries in their shift summary
- The shift worker should discuss an issue with the shift expert before making extra logbook entries

Shift Worker Tasks
- Check the information in the Short Term Schedule and GENERAL INFORMATION, for every shift
- Come to your shift in time for the shift change, 10-15 minutes before the start of your shift.
- Use the HBRUN logbook for automated and run-specific entries and screenshots, see https://logbooks.jlab.org/entry/4048698
Make the following log entries ONCE per run
- Screenshots: submit to logbook only if you capture the information with beam ON
- Beamline Overview, in VNC or Web Browser
- CLAS12 Trigger rates and DAQ status
- Upload monitoring plots to logbook
- Standard spectra (mon12): inspect all monitoring histograms ' and carefully compare them to the corresponding reference histograms: reference, current, and 5 most recent runs, see link under tab Useful Links
- You can choose a different reference run if you are confident what you are doing, the reference numbers refer to logbook entries.
- Standard spectra (mon12): inspect all monitoring histograms ' and carefully compare them to the corresponding reference histograms: reference, current, and 5 most recent runs, see link under tab Useful Links
Once per shift:
- Fill the shift checklist
- Log screen shots of RICH temperature and scaler maps. Log in RICH logbook.
Regularly:
- reset & check spectra frequently (every 30 - 60 minutes)
- Some plots in the online mon12 have a choice of histogram sets per sector, select buttons at the bottom of the plot. That means you have to look at all sectors for these histograms.
- The logbook entry shows all histograms.
- Log the strip charts in time intervals according to the x-axis time span, via right-click on the screen and selecting "Make Elog Entry". Make sure NOT to submit to ELOG.
- Beam current and position strip-charts (CS-Studio -> Beamline -> Strip Charts)
- You can also see beam charts in the Web Browser: Upstream/Midstream Halo Counters, Downstream Halo Counters, Beam Currents, BPM Positions
For REMOTE Shifts (offsite):
- Zoom for 24-7 communication with counting house: https://jlab-org.zoomgov.com/j/1619881100
- Passcode REQUIRED: 927417
- Remind the expert in the counting house to restart their zoom, if necessary
- Remote VNC connection instructions: https://logbooks.jlab.org/entry/3906039
- All necessary applications should be avaible from the desktop menu (left/right click on the desktop)
- EPICS GUIs should be accessed ONLY via the desktop menu or by running clascss-remote.
- Remote Demonstration Video (150 MB)
ATTENTION: If you plan to take (a) remote shift(s), you MUST test your setup (including VNC connection) at least 24 hours before your first shift!
