BONNER CYLINDER SET FOR NEUTRON SPECTROSCOPY AT HIGH ENERGY ACCELERATORS

Abstract

Abstract At particle accelerators, the knowledge of neutron spectra is important for radiation protection to improve the accuracy of dose measurements, for activation and radiation damage studies. Classical Bonner sphere spectrometer is a common reliable tool for this kind of measurements. Here we present a new set of cylinders with TLD cards as a sensitive element to be used for neutron spectroscopy in a wide energy range for continuous and ultra-short pulse radiation. A simple layout, relatively small dimensions and weight, as well as implementation of common materials providing low construction costs make the set useful for spectroscopic purposes. The unfolding results for various simulated radiation scenarios are also presented.
