Counting house: 6000(*), 5503, 6666 | Run coordinator: 757-270-8916 | MCC: 7047(*), 7046, 7048 | Crew chief: 7045 | Guard house: 8522

Before the start of your shift: read and understand the Safety Documentation for this experiment.

  • You must then sign in the Yellow Binder in the Hall C Counting House!
 NOTE: Read about How to operate the Hall-C Radiator (J/Psi Experiment)

Detailed instructions for Shift Takers are available on the How-to page. If you encounter problems, look first at those instructions for assistance.

Current Run Plans

Your Responsibilities

Shift Leader

  • Communicate clearly and effectively with shift crews and MCC (7047), and log any status information to the HCLOG
  • Maintain and update the Shift Summary detailing the events which occur while on shift
    • This is done by starting the summary as a log entry titled "X Shift Summary" where X = Day, Swing, Owl
    • Save & edit the summary after ANY event of interest occurs
    • This provides the readers with an up-to-date play by play of the current shift
    • See example: https://logbooks.jlab.org/entry/3402742
  • Consult the daily run plans and communicate with [1] whenever problems happen that cannot be solved by shift workers.
  • Maintain data taking quality and an efficient use of beam time.
  • Log the following in a shift summary in the Hall C Logbook:
    • run list (describing the goal of this run: eg production on LH2, BCM calibration...) and report main statistic numbers
    • any major events, including accesses

Target Operator

  • Assist the shift leader and third person with their duties

Third person

  • Make certain that the Hall-C Alarm Handler process is running. See Hall_C_Alarm_Handler.
    • If there are any alarms being ignored or silenced, find out why and enter this in the logbook.
    • Log any alarms when they occur.
  • Start and stop the DAQ. Record the purpose for every single run in the "Run list" binders. Blank forms for Fall 2018 can be found here.
  • Analysis instructions are given for each experiment's wiki.
  • Compare replay histograms with the sample ones and report to shift leader any unexplained differences. Hclog them.
  • Fill shift checklist once per shift (for guidance, please see the Information for Shift Takers).
    • An older Shift Checklist file, which also includes help for locating items, should be available here.
