- Change in electronics in the NIM crate in Messhuette:
- Set and fix delay in TPC module to be [minimum + a little]
- Move analog passive delay (from input of TPC module as it was) to after the analog output of TPC module for ADC
- Schematic diagram:
- Rough adjustment of electronics parameters using test pulses (t=0 for sc time references, t=900ns V=-140mV for Axx, t=1700ns V=-140mV for Dxx).
- Gain of the TPC module is set to get analog out around 1.5V.
- Delay of the TPC module is set to minimum + a little. Timing at NIMOUT is t=1200-1400ns for Axx, 1900-2100ns for Dxx.
- Multi-hit TDC V1190 has been installed (replacement for V775 TDC). Channel assignment is listed here.

- checked which channels of the TPC modules (amp./discr/delay) are broken.- List of the broken channels (link) -- NisanYaprakBenal - 2026-10-26
