NEUTRON AND γ-RADIATION FIELD CHARACTERISTICS FOR 14 MeV NEUTRON GENERATORS USED WITH A STILBENE-CRYSTAL SPECTROMETER

摘要

Neutron and γ-ray field characteristics have been examined for two 14 MeV neutron generators by the use of spheres and special cylindrical systems composed of various materials. Measurements have been made on the energy resolution of the spectrometer fitted with a stilbene scintillation crystal in relation to monoenergetic 14 MeV neutrons and the broadening of the monoenergetic neutron spectrum due to interaction with a target material block.
