Study on detecting spatial distribution of neutrons and gamma rays using a multi-imaging plate system

In order to measure the spatial distributions of neutrons and gamma rays separately using the imaging plate, the requirement for the converter to enhance specific component was investigated with the PHITS code. Consequently, enhancing fast neutrons using recoil protons from epoxy resin was not effective due to high sensitivity of the imaging plate to gamma rays. However, the converter of epoxy resin doped with 10B was found to have potential for thermal and epithermal neutrons, and graphite for gamma rays.
