=Day 1 (December 21st)=

====Notes====
* Current at -1200 V: 200.9 &mu;A (beam off)
*Some double peaks and very large signals present - noise of some sort?
*Background rate (-1200 V, beam off, 3 mm collimator): ~4 kHz
**Threshold: -19.5 mV
**Rise time: 2.5 ns (without averaging), 2.9 ns over 10 sweeps
**Amplitude: ~75 mV over 10 sweeps
*Having the corridor lights on does NOT create enough light to trip the PMT and is acceptable! (Current goes up by 0.1 &mu;A)
*Peak current estimate at -1100 V: 44 mA
**Amplitude: 2.2 V
**Width: ~20 ns
