A97 had 1000e tuning from Timon on YARR during last period. Checked with RCE+FEB calibration looking OK

Day shift: UCSC T788 setup continues during MD. One main issue to resolve is the dead Trg-10 for Caladium. T578 needs both Trg-10 (NIM for Caladium) and Trg-11 (TTL for HGTD). Didn't manage with connect with Doug to debug the dead Trg-10, but he passed on a schematic for the ESTB trigged patch scheme:
 |  | |
|---|---|---|
| Counting house patch panel. Note the very taught LEMO cable leading to J10. | Yellow=Trg-10 (NIM); Cyan=Trg-11 (TTL) at Caladium rack. The 8.5us delay between them seems to commensurate with the delay panel settings: (-102010) - (-110488) = 8478 |
The issue with Trg-10 is not obvious: EVG rear expansion board ch 11 (LVTTL?) is one of the inputs (the other input is EVG Front trigger 2) to the Lecroy level adaptor in compl mode tuning that into a -1a 1.2V and 300ns width NIM. The only part looking suspicious is the LEMO cable taking the NIM output to J10 looks very tight. Replaced that part with a slightly longer cable. This did effectively bring the Trg10 NIM signal back to Caladium rack but signal shape weak. Decided to connect J10 directly to EVG rear 11 to send TTL signal over long path to tunenel and used TTL->NIM at caladium rack for a much more solid NIM signal to TLU.

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.
