Random pulsing of neutron source for inelastic neutron scattering gamma ray spectroscopy |
摘要 |
Method and apparatus, for use in the detection of inelastic neutron scattering gamma ray spectroscopy, effect data acquisition efficiency enhancement by operating a neutron generator such that a resulting output burst of fast neutrons is maintained for as long as practicably possible until a gamma ray is detected. Upon the detection of a gamma ray the generator burst output is terminated. Pulsing of the generator may be accomplished either by controlling the burst period relative to the burst interval to achieve a constant duty cycle for the operation of the generator or by maintaining the burst period constant and controlling the burst interval such that the resulting mean burst interval corresponds to a burst time interval which reduces contributions to the detected radiation of radiation occasioned by other than the fast neutrons.
