Eu152 Calibration
- HPGe calibrated using Eu152 source
As of 9/28/21
The calibration used to map from ADC channel number to KeV is:
Where x = channel 9 of the ADC and is input as PADC.PADC785N[9].
Total Efficiency
This is total efficiency using the Gadolinium foil as the source.
Then find detected rate using HPGe
Divide (detected rate) by (theoretical rate) for total detector efficiency
