Run Plan
Production running cycling through targets:
- JD80-212 80um diamond, 200 nA beam current
- 800M events for 0/90 deg and PARA setting
- 800M events for 0/90 deg and PERP setting
- 800M events for 45/135 deg and PARA setting
- 800M events for 45/135 deg and PERP setting
- 400M events with 4.5×10-4 Al 40um radiator (on goniometer!), 300 nA beam current
- Set new reference for amorphous radiator in CBREM GUI.
- Runs should be no longer than 2 hours.
- Keep the state of the production cycle on the whiteboard up-to-date.
Special instructions
- Put comments for each run in the window opened by the DAQ.
- The comment should at least contain the following information "<radiator> <PARA/PERP>, <beam current>, LH2 target, <typical trigger rate>, <typical live time>, <issues if any>"
- Example: "JD80-212 80um 45/135 PARA, 200nA, LH2 target, 81kHz, 93% live time"
- Note: due to a software issue run comments may not show up in RCDB, but they are saved by the DAQ and will be later added to the RCDB entries.
- Set a new amorphous reference in the CBREM GUI each time the amorphous radiator is used.
- Be sure to hit the "PARA" or "PERP" button in the CBREM GUI when switching diamond targets. Otherwise the diamond alignment may be in an undefined state and the experiment may be flooded with low-energy photons.
- Watch for locked-up FCAL HV bases towards the end of a run and clear them before starting a new run. See [1].
- Watch the DAQ lifetime when beam is on. Sometimes it drops to 0%. Just stopping and restarting the run fixes this issue in most cases.
- New hdops wiki feedback form is here please use this to report confusing or outdated wiki instruction pages.
Medium Term (1 week)
- No special plans.
