Before the start of your shift:

Responsibilities

Shift Leader

  • Communicate clearly and effectively with shift crews and MCC, and log any status information to the HALOG
  • Maintain data taking quality and an efficient use of beam time.
  • Follow the directives in the COO
  • Log the following in a shift summary in the HALOG:
    • run list (describing the goal of this run: eg production on LH2, BMC calibration...) and report main statistics numbers
    • any major events, including accesses

Target Operator

  • Watch the target, see Target Info
  • Assist the shift leader and third person

Third person

  • Start and stop the DAQ.
  • Do online replay of all production runs;
  • Compare replay histograms with the sample ones and report to shift leader any unexplained differences. Halog them.
