Revision as of 23:43, 10 February 2023
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 |
2/10/23 Same procedure as 2/3/23, just changing HV applied to He3 detector to values of 1300V then 1100V.
