The first time we read out tagger crates with the trigger. Timing offsets were adjusted.
Trigger type: PSC
Converter: fork frame (0.1 X0)
FADC samples: 100
2 top plots: Position of TAGH and TAGM pulses (maximum amplitudes ) in the fadc read out window.
- TAGM and TAGH are aligned. The TAGM peak is narrower than TAGH due to the smaller
particle propagation time.
2 botom plots: TAGH/TAGM occupancies
- groups of counters with different width can be seen in theTAGH occupancy
Trigger latency studies:
fadc offset TI file
975 0xCA TAGM/data/tagm_calib_234.0
975 0xA2 235
925 0xA2 236
925 0x96 237
895 0x96 239
895 0x89 240 (TI delay too short)
895 0x96 241
