Abstract

An ionization chamber with Frisch grid is used to detect the recoil protons induced by fast neutrons in an advantageous 2 Pi geometry. The working principles of the detector are explained. Recoil proton spectrum measurements are made at several incident neutron energies below 2 MeV using four radiator foils of different thicknesses. These measurements permit a proton energy calibration of the detector and the determination of proton stopping powers for the radiator foil material. Proton recoil spectra are interpreted by Monte Carlo calculations with the aim of understanding closely the spectrum shape and to obtain the total number of proton recoils.
