Summary for the CASTID shift RO Aug 16, 2025

We measured four TJ-Monopix2 DUTS with HV/HVC frontends using AIDA mode in a stacked telescope configuration. We used 800MeV protons at low flux settings from very low to high.

We took two high statistics runs on each of the 4 rates. Then we repeated the measurements at medium and high settings for following readout speeds (40 is the default): 30, 20, 10, 2 (minimum).

At increased readout speed, we shoudl be able to recover (part) of the efficiency drop at increased rates.

- Occasionally (maybe a few times an hour but in clusters) we got 8b/10b errors. If so, they all came from the W02R01 DUT using BDAQ board #063/50 and the TLU adapter 1. This is the main source of having 'crap' data

- About 3 times during the test beam, one of the chips (each time a different one) stopped sending data which was possible to recover with a power cycle.
