Spectrometer for pulsed and continuous electron and photon radiation

Abstract

A few-channel spectrometer for the determination of absolute fluence and energy distributions (spectra) of electrons and photons was developed. This spectrometer consists of thermo-luminescence detectors (TLDs) placed in a stack of 30 different absorbers. From the measured depth dose curve, the impinging particle spectra can be derived via unfolding methods (data evaluation). In mixed radiation fields, it is necessary to take information into account in addition to the measured depth dose curve (additional pre-information) for the data evaluation. The spectrometer was successfully applied in different areas.
