  • HPGe calibrated using Eu152 source
CH Eu152 Calibration Spectrum.png

As of 9/28/21

The calibration used to map from ADC channel number to KeV is:

[math]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] (line\ intensity)\ (incident\ thermal\ neutrons\ per\ second)\ (\sigma_{total})\ (MCNP\ fudge\ factor\ from\ Paul\ ~4) [/math]
