Classification of the low-energy neutron spectra behind the shield of the accelerator of the institute of high-energy physics
The investigation and classification of neutron energy spectra is one of the most complicated and important research problems. In order to eliminate the influence of possible systematic errors upon the classification, one must make a representative sampling of data which were measured with a single technique within particular energy limits. For this purpose, on the 70-GeV proton accelerator of the Institute of High-Energy Physics, there were measured more than 100 spectra behind the shield at points which can be characterized by variations of well distinguishable parameters such as thickness and composition of the biological shield, inhomogeneities (passageways and labyrinths) in the shield, the source-shield-detector geometry, and the specific conditions of accelerator operation.
