PEPPO Spectrometer: | 151.3 A |
Set HV to Detectors
Signal channel | HV dac | HV (V) | |
Detectors #1 | A1 | 2.4 | 960 |

Annihilation Counter Runs
- Signal Definitions for Trigger logic
- SYNC:=60 Hz sync pulse 200 micro seconds long
- Det1:= Annihilation Counter #1 (HV1)
- Det2:=Annihilation Counter #2 (HV2)
This run 2902, Int_Ch14 histogram. Why there is negative?
