A fast neutron spectrometer for reactor flux measurements

Conference ·
OSTI ID:4877819
A neutron spectrometer is constructed that may be employed for neutrons with energies from about 0.5 to 5.0 Mev. The design is a modification of a recoil-proton telescope, and employs a silicon surface barrier diode as a detector. Difficulties with neutron-induced reactions in the diodes themselves from neutrons above 5 or 6 Mev, which affect the performance of ''sandwich- type'' silicon diode neutron spectrometers, are eliminated. A measurement of the neutron spectrum in a collimated beam from a reactor is made, which shows that the instrument provides a satisfactory means of determining the energy distribution in a non-monoenergetic flux.
