Spring 2016 Run Planning Meeting
- In preparation for the coming run need to perform complete tests of the detectors: should start taking cosmic data early next week. Expect to have physics data taking at least at the end of the run (once the calorimeters are calibrated).
- FDC was turned on few days ago. One positive HV channel (second package, most downstream cell, side HV sector) draws huge current, can be operated at 200V below nominal. The problem started in early December. Most likely it's outside of the gas volume since the filed HV is not affected. It has been checked that it is not the HV module. Fixing will require access to the HV connection (at the bottom of the second package) and it can't be done now. If needed (still 1% of the sensitive area) can be done during the summer. CDC has not been turned on yet.
F125 Update
- Naomi reported on the test of the f125 firmware status (see link above). She compared the emulated results using the raw data with the firmware quantities. After fixing with Cody several problems, only a few and very rare issues remain as listed in the link. The issue with the short events initially caused crushing of the analyzing software but was eventually fixed by David L.
