Before the start of your shift:
- Read, understand and sign the safety documentation of the experiments.
Responsibilities
Shift Leader
- Communicate clearly and effectively with shift crews and MCC, 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 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 with their duties
Third person
- Start and stop the DAQ.
- Online replay of all production runs, as described in the online data analysis instructions:
- godvcs
- analyzer
- .x online.C+("detectorL", NNNN);
- .x online.C+("calo", NNNN);
- .x online.C+("physics", NNNN);
- 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). If both the Shift Checklist and the Shift Checklist How-to need to be modified, the original .doc files can be obtained from | DVCS ELOG entry 255.
- The shift leader or TO can help.
