Comparison of Neutron Fluxes Measured by 3He-Gaseous Proportional Detectors and Calculated with the PhiTs Package
Our calculation and measurement have been made for a system consisted the Pu-Be source, the gaseous detector and moderators. As result we have got a satisfactory agreement between calculation and experiment data and have approved using the PhiTs system for this purpose. Our experimental setup does not let us make a conclusion about the source spectrum. A dependency of the particle number absorbed in polyethylene with boron from boron concentration was analyzed.
