Abstract

The neutron energy spectrum at the beam port has been measured at many boron neutron capture therapy (BNCT) facilities worldwide. At Heavy Water Neutron Irradiation Facility of Kyoto University Research Reactor (KUR-HWNIF), two types of neutron spectrometers—the Simple Multilayer Spectrometer (SMS) and the Cylindrical Hemisphere-Accurate Remote Multilayer Spectrometer (CHARMS)—were recently developed to measure the neutron energy spectrum. This paper investigates the characteristics of each neutron spectrometer in measuring the neutron energy spectrum at BNCT irradiation field, with a focus on their dependence on the angular distribution of the incident neutron beam. Additionally, an overview of the CHARMS prototype designed to verify online and remote operation from outside the irradiation room is provided.

期刊介绍： Applied Radiation and Isotopes provides a high quality medium for the publication of substantial, original and scientific and technological papers on the development and peaceful application of nuclear, radiation and radionuclide techniques in chemistry, physics, biochemistry, biology, medicine, security, engineering and in the earth, planetary and environmental sciences, all including dosimetry. Nuclear techniques are defined in the broadest sense and both experimental and theoretical papers are welcome. They include the development and use of α- and β-particles, X-rays and γ-rays, neutrons and other nuclear particles and radiations from all sources, including radionuclides, synchrotron sources, cyclotrons and reactors and from the natural environment. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. Papers dealing with radiation processing, i.e., where radiation is used to bring about a biological, chemical or physical change in a material, should be directed to our sister journal Radiation Physics and Chemistry.
