J. Hassard et al., CVD DIAMOND FILM FOR NEUTRON COUNTING, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 416(2-3), 1998, pp. 539-542
A detector capable of measuring fast neutrons based on proton recoil p
rocess has been developed. It consists of a 1 mm thick paraffin wax pr
oton recoil radiator attached to a CVD diamond him charged particle de
tector. Its radiation hardness and low gamma sensitivity make diamond
advantageous over other semi-conductor materials as a neutron counter.
Measurements have been carried out with an accelerator neutron source
and it has been shown that fast 2.85 MeV neutrons can be detected wit
h improved efficiency and good gamma discrimination. Possible applicat
ions of this detector are also discussed. (C) 1998 Published by Elsevi
