Eu152 Calibration
- HPGe calibrated using Eu152 source
As of 9/28/21
The calibration used to map from ADC channel number to KeV is:
[math]\displaystyle{ Photon Energy = -36.2928 + 0.449519 x - 0.000000861277 x^2 }[/math]
Where x = channel 9 of the ADC and is input as PADC.PADC785N[9].
Theoretical Efficiency
This is total efficiency
[math]\displaystyle{ (line\ intensity)\ (incident\ thermal\ neutrons\ per\ second)\ (\sigma_{total})\ (MCNP\ fudge\ factor\ from\ Paul\ ~4)\ =\ Theoretical\ Rate }[/math]
