Description
In the work, we studied the influences of dead layer thickness on the whole gamma
spectrum response for HPGe detector by using Monte Carlo simulation. From the
simulated relation of the FEPEs and the dead layer thicknesses, the dead layer thickness
of 0.567 mm was derived which increased compared with the nominal value of 0.46 mm
from manufacturer after 4 years of operation. The multiple scattering region and peak
decreased with different rates and the valley region of the forward scattering photon
increased quickly when the dead layer thickness increased. The energy dependence of the
P/T and the general range were also carried out. The results showed that the effect of the
increase in dead layer thickness on regions in the spectrum was not the same. Through
this study, among several scintillators, it was possible to find a HPGe detector suitable for
the purpose of the study
