HV Cables on DCs: Sense-A2, Guard-A3 and Field-A4
| HV Chan | Description |
| N470 Ch 0 | Drift Chamber Sense |
| N470 Ch 1 | Drift Chamber field |
| N470 Ch 2 | Drift Chamber guard |
| N470 Ch 3 | nothing |
| N471 Ch A | R1 drift |
| N471 Ch B | R1 foil |
| N471 Ch A | Front and read PMTs |
HV cables on scintillators: Front && rear PMTs-A8. Hv settings 1150 Volts(works). In counting room front-A1(BNC) and rear-A2(BNC).
Plan: A3 should be gate. A4 - Start for TDC. A12-trigger.
HV Settings on drift chambers S:F:G=1400:-700:980
Setup TIming
Accelerator sends the Gun gate to HRRL counting room on channel BM
The accelerator Gun gate starts our Stanford pulse generator.
- The Stanford pulse generator outputs 2 pulses
- one pulse is for the ADC gate and G1 trigger for V1495
- The second pulse create a trigger for the DAQ
