Experimental considerations on the determination of radiation fields in an electron accelerator

Abstract

The determination of the different radiation fields in an electron accelerator requires the use of selected radiation detectors, in this work we describe the experimental considerations on the determination of the intensity of electrons and X-rays generated by bremsstrahlung in an experimental electron accelerator covering the energy range from 80 keV to 485 keV. A lithium- drifted silicon detector, a high-purity germanium detector, a scintillation detector and a PIN diode were used in the experiments. Spectroscopic measurements allowed us to verify the terminal voltage of the accelerator. The PIN photodiode can measure the intensity of X-rays produced, with this information, we could determine its relationship with both the electron beam current and the accelerating voltage of the accelerator.
