General Responsibilities

The DCH QA shifter is responsible for ensuring the quality of the DCH data. To this goal, you are required to:

Check on things at IR-2 at least once or twice a day.

• Read the BaBar and DCH electronic logbooks for the current shift, and previous shifts since you last did this.
• Talk to the DCH Operations Manager and/or the BaBar Shift Leader, to see if there are things you should watch for in the data.

Check the online calibration

• Problems in the data could be due to bad calibrations.
• Electronics problems could be reflected in bad calibrations.

Check the data-quality monitoring histograms.

• Run ``Offline'' Fast Monitoring for a few good runs (physics or cosmic) every shift.
• Check Prompt Reco Monitoring histograms for new outputs.
• OR use the new Multi-run QA Web form to get a list of recent runs processed by OPR, with direct links to the histograms.
• Follow the instructions and check the Tracking and DCH histograms.
• If there are problems, add notes for the specific runs to the logbook.
• Update the Electronic Logbook.

Communicate and share information.

• Let the DCH Operation Manager know every day when you have done your duty: send a mail that sumarizes your daily activities.
• The DCH Operation Manager will contact you one day before you start/finish your shift.
• Get news from the previous shifter and the BaBar shifter.
• Read the Current Problems page for a list of known, ongoing problems.
• Read the DCH and BaBar electronic logbook.
• Write everything on the DCH electronic logbook!
