Issues/Reports
- Wednesday when doing the cosmic raw run the FP pulser rate was set to 2kHz and forgot to reset it back to 100Hz afterwards. So we were running with 2kHz the whole time since. Now set back to 100Hz (Beni). -> Sasha said it wasn't a big problem since it didn't change deadtime
- In general, beam conditions have been really poor. We continued taking data but made sure to mark some of the runs while ACC was troubleshooting problems with the injector.
