Benedikt Zihlmann is inviting you to a scheduled ZoomGov meeting.
Topic: Start Counter

Agenda
- Start Counter status:
- Start_Counter_Operations
- Geometry: SC match to tracks
- Preparation for next year's running
- FADC250_READ_THR 120: (Runs 41384, 120848) needs to be higher, 20 ADC counts above base line is too low. Full scale of 4096 bits is 500mV with a base line around 100 leads to 500mV/(4096-100) = 0.12mV / ADC count: So a setting of 20 ADC counts above base line corresponds to only 2.5mV
- DSC2_THRESHOLD 50 60: this corresponds to 50mV for discriminator threshold setting.
- while adc readout threshold is clearly set too low the discriminator threshold may be too high. Need to find compromise and better match.
