Shift Leader Responsibilities

  • Calculate ABU's when in production mode by counting good Coulombs per run: 150uA each hour = 0.54C. 1hour runs. For each hour long run(s) take #good-Coulombs/0.54C = #ABU's (even when running at a lower current, obsolete method: https://logbooks.jlab.org/entry/3785102)
  • Communicate clearly and effectively with shift crews and MCC (7047)
    • arrive ~10 min. early to your shift to talk with the previous shift crew
    • Answer the phone
    • Communicate with the RC
  • Consult the Daily Run Plan and contact the run coordinator whenever problems happen that cannot be solved by shift workers
  • Log any status information to the HALOG (Make sure to log in!)
  • Maintain data taking quality and efficient use of beam time
    • Use Panguin to evaluate data quality
  • Post Snapshots with HALOG of important information at least twice a shift.
  • Keep track of beam time accounting
  • Follow the directives in the COO!
  • Log the following in an end of shift summary in the HALOG:
    • run list (describing the goal of this run: eg production on Pb, BCM calibration...) and report main statistic numbers
    • any major events, including hall access (in addition to making log entries when they happen)
  • Complete the Shift Checklist at the beginning of the shift - see Instructions
    • Note: There is a convenient script in ~/cameronc/SL/auto-SL.sh which will walk you through the steps of the shift checklist and provide easily copyable text-outputs for easy entry into the checklist and comparison with expectations
  • Print off additional run sheets (printer "chax"): https://logbooks.jlab.org/entry/3700479
  • A PREX analysis shift worker will be on hand for most shifts (although not required by the COO) to help out in high demand situations. Please coordinate with them as well.
  • Read Common Problems for information on how to deal with common issues cropping up
