TLDR
A beta spectrometer close to 4π configuration based on silicon detectors is developed and the influence of self-absorption has been studied by means of Monte Carlo simulations and the source preparation technique has been optimized consequently.
Abstract
The accurate measurement of beta spectra is highly important in numerous fields such as nuclear energy, nuclear medicine, ionizing radiation metrology and fundamental physics. We have developed a beta spectrometer close to 4π configuration based on silicon detectors. The influence of self-absorption has been studied by means of Monte Carlo simulations and the source preparation technique has been optimized consequently. The measured spectra from 133Ba and 36Cl decays have been compared with PENELOPE simulations.
