Signals were observed in the LDS on the Mini DC prottype detector.
The apparatus
The following Voltages were established on the Driftcahmbers wires
| Distance | HV settings | |
| Wire | Volts | |
| Sense | 1800 | |
| Field | -750 | |
| Guard | 750 | |
The Scintillator mounted on top of the Chamber was set to -900 Volts
Noise Level Measured by scope in infinite persistance mode indicate that the Mini Prototype with plastic feedthroughs (Plastica) has noise levels spanning +/- 10 mV. A PMT connected to a scintillator shows noise levels around+/- 2.5 mV.
A few Characteristic scope pictures of event triggered on the chamber output.
