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

HV Counts
1492.67 1532.5 +/- 36.67
799.15 1336.5 +/- 2.121
396.83 1193.5 +/- 54.477
197.19 1035.5 +/- 40.305
4.88 562.5 +/- 2.121

NO source on face of HpGe detector

HV Counts
1492.67 167.5 +/- 7.778
799.15 149.4 +/- 34.648
396.83 127.5 +/- 7.778
197.19 121 +/- 4.243
4.88 332 +/- 35.355


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

Counts/10s

Cf Source out of containment to He3 detector

HV Counts/10s

Cf Source in containment to He3 detector

HV Counts
