Summary
- Ran with beam most of yesterday, collecting 1.2C
- Beam tripping increased and MCC had to drop us to 30 uA during owl.
- This morning MCC did some beam studies and feels confident that the trips will be reduced now.
- Provakar and Arun investigated the BBCal FIFO but discovered that the upstream summing module is the actual issue. This will take a 1 hour access to fix.
