Neutron Spectrometry by Diamond Detector for Nuclear Radiation

Experiments on fast neutron spectrometry using the nuclear radiation diamond detector inside a horizontal channel of a water-cooled and water-moderated reactor are described. It is shown that the diamond detector enables neutron spectra to be measured within the energy range of 0.3 - 10MeV against reactor gamma-radiation background and has radiation resistance higher than that of conventional semiconductor detectors.
