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=

{| border="1"
| 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=

{| border="1"
| 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=

{| border="1"
| HV|| Counts/10s
|-
|
|}

=Cf Source in containment to He3 detector=

{| border="1"
| HV|| Counts
|-
|
|}

2/10/23
Same procedure as 2/3/23, just changing HV applied to He3 detector to values of 1300V then 1100V.
