Default HRRL running Conditions
| Pulse Width | Rep Rate | Energy | |
| 8 mA | 100 ns | 1 Hz | 3 MeV | 
cable names
| CH ID | Description | 
| 2223A1 | Front Scintillator | 
| 2223A2 | Rear Scintilaltor | 
| 2223A3 | ADC Gate From counting house to Experimental Cell | 
| 2223A4 | TDC start pulse from counting house to experimental cell | 
| 2223A5 | Coincidenc between front + rear Scint + Gun pulser to scaler channel 8 | 
| 2223A6 | Metalica sense wire 4 | 
| 2223A7 | G0 MCLK for | 
| 2223A8 | Plastica sense wire 4 | 
| 2223A9 | scaler channel 4 | 
| 2223A10 | Front scintillator to ADC | 
| 2223A11 | scaler channel 1 | 
| 2223A12 | DAQ trigger | 
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
 
Singles scaler counts
