Before the start of your shift: read, understand and sign the safety documentation of the experiments.

Very detailed instructions are available in the HRS / DVCS how-to page. If you encounter problems, first look at those instructions for assistance.

  • Maintain data taking quality and an efficient use of beam time.
  • Follow the directives in the COO

    • run list (describing the goal of this run: eg production on LH2, BMC 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 [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.
