This is where I write down what I'm doing
1/13/23 : Turned on HpGe HV to 1500 and learned about analog to digital signal processing
detected signal rate -vs- HpGe Voltage
Cs-137 source on face of HpGe detector

1/27/23 : Turned on He3 detector, adjusted to find counts with Cf source in containment and out of containment
2/3/23 : Same as 1/27, adjusting discriminator voltage and recording counts with Cf-252 source. Encountered strange effects of higher counts with source away at low QD voltage. Sets of measurements notably inconsistent.
HV on He3: 1208V
Amplifier Gain: 21.5
Cf Source out of containment to He3 detector
Cf Source in containment to He3 detector
