The scope pictures show the PREamp output on Channel 2 given the input pulse shown on Channel 1 that is input directly onto the sense wire.
The CAEN N470 power supply was used to establish voltages onthe drift chambers. A SHV tee was used to allow a single HV channel from the CAEN power supply to power both chambers in parallel. The Drift chamber voltages settings were set according to the table below. The current column indicates the total current drawn from both chambers.
| HV settings | ||
| Wire | Volts | current (A) |
| Sense | 1500 | 19 |
| Field | -800 | 19 |
| Guard | 800 | 0 |
