5:26   New version of YARRproducer stabilized the synchronization between MIMOSA and RD53a readout. Previous version used local event counters with no direct check of event ID to confirm synchronisity. It was seen that block of e.g. 1000 events are offset by a few events between MIMOSA and RD53a, and then this offset would slip every ~1000 events so that sometimes by chance the synchronization is achieved by luck and then slips off again after a while. New version defies the RD53a event number using the TLU distributed event number (offset by 1) to automatically achieve synchronization.

5:40  Tried to turned the Synchronous FE but way too noisy.

5:50  Remote rotated DUT (B53 50x50um pixel 150um thichkness) to ~60 deg tilt. Also needed to move +x by 5mm to recenter.

Data with B53:

Run 782-782 tilt configuration

7:00  Requested access to change DUT to A97 (25x100um oixel). and mounted at 0 degrees. Also checked the Trg-10 NIM signal - now back.

8:10  Lowered particle rate to ~4 clus/mimosa and 0.6/pulse on RD53a 2/3 FE area. Hit spread pretty uniform.

8:16  Started low rate run 789. Beam spot X looks a bit off - centered at 340.  

8:40  Stoped Run 789. Moved RD53a DUT by X+4mm.

8:42  New run 790 after DUT +x move.

9:00  MCC called to take away beam briefly for primary beam energy change. Will still come back to ~12.2 GeV secondary.
