Counting house: 5503, 6666 & 6000 | Run coordinator: 270-8916 | MCC: 7046 & 7047 & 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!

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


Your Responsibilities

Shift Leader

  • Communicate clearly and effectively with shift crews and MCC (7047), and log any status information to the HCLOG
  • 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

  • Start and stop the DAQ. Record the purpose for every single run in the "Run list" binders. Read fixme to create more blank forms.
  • Online replay of all production runs (twice), as described in fixme. first replay the first 50 k events, check online plots (see next bullet), then run a full replay.
  • Compare replay histograms with the sample ones and report to shift leader any unexplained differences. Hclog them.
  • The shift leader or TO can help.
