Back to How-To and shift info

Counting house: 5501 & 5507 | Run coordinator: 876-1787 | MCC: 7046 & 7047 & 7048 | Crew chief: 7045 | Guard house: 8522

Before the start of your shift: read, understand and sign the safety document in the counting house (Yellow binder). Online version available from safety documentation

Very detailed instructions are available in the Complete How-To and How-to from DVCS experiments. If you encounter problems, first look at those instructions for assistance.

Your Responsibilities

Shift Leader

  • Main point of contact between Run Coordinator/MCC and Shift workers.
  • 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, optics calibration, ...) and report main statistic numbers
    • any major events, including accesses

Target Operator

  • Use the target mover gui as required to change targets (TO instruction)
  • Post target status, strip charts to halog once per shift
  • Start and stop the DAQ. Record the purpose for every single run in the "Run list" binders. Read [this] to create more blank forms.
  • Online replay of all production runs (twice), as described in the online data analysis instructions. 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. Halog them.
  • The shift leader can help.
