Shift Leader

• 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 minutes 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.
  • Include- Hall A tools, BPM strip-charts, and BCM strip-charts.
  • Include any snapshots of the details after a change
  • Please feel free to post these Snapshots more often
  • Sample screenshots to make during shifts (examples below during no-beam conditions, purely descriptive): collimator temp, Compton ion chambers, bpms, vacuums, parity controls, FFB, raster, ioc chamber
    • Collimator and Beamline temperatures
    • Hall A Beamline monitors, and Compton and Moller magnets, and bleedthrough check - useful for evaluating beam set up and tune
    • Ion Chambers
    • FFB system - these examples show the system while inactive - check a more recent log entry with active FFB for a prescriptive example
    • Hall A Raster
    • Hall A Tools, magnets
    • Hall A Target status
    • Scaler GUI
    • Injector Loss Monitor - useful for diagnosing large Aq widths and noise problems
    • Charge Feedback Monitor
    • Compton
    • Target motion and mask
    • Beamline Vacuum
    • Parity Controls
• 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 GEp-V 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
