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 [ https://hallaweb.jlab.org/index/safety-docs/current/ documentation] of the experiments.

Very detailed instructions are available in the How to HRS. 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 HALOG

• Keep track of beam time accounting

• Consult the daily run plans and communicate with run coordinator whenever problems happen that cannot be solved by shift workers.

• 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 (see TO ADD: TARGET GUI LAUNCH INSTRUCTIONS AND SCREENSHOT)

• 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.

• Fill shift checklist once per shift (for guidance, please see the checklist how-to). [go here to find blank copies of the shift check list and the shift check list how to]

• The shift leader can help.
