NINO LCO measurements - simulationsShowed that we can reach for a hybrid detector :-min. detectable charge of 1.5 fC @ 200 ps rms
- jitter < 150 ps for charges > 2 fC
Pre-amp + LCO - simulationsShowed that we can reach for a hybrid detector :- min. detectable charge of 0.5 fC @ 250 ps rms
- jitter < 150 ps for charges > 0.8 fC
