Fast Neutron Spectroscopy by Proton-Recoil Proportional Counting

Design, Construction, and Evaluation of a Facility for the Simulation of Fast Reactor Blankets.

“…An attempt will be made to use prompt capture gamma spectroscopy to perform a neutron balance inside the blanket assembly. Measurements of the differential neutron spectrum will be made at various distances into the blanket assembly with a proton recoil spectrometer, using methods similar to those developed by E. F. Bennett (34,35) at ANL. The differential neutron spectrum in the blanket assembly will also be determined by unravelling the incident neutron spectrum from the component gamma activities induced in a mixed-powder foil, and also, possibly, by measuring the recoil doppler broadening of the hydrogen capture gamma peak.…”

Neutron Spectrum and 10B(n,α) Measurements in ZPPR-15

“…Techniques for proton recoil spectroscopy at Argonne were developed primarily by E. F. Bennett and T. J. Yule. Their report, ANL-7763, includes detailed discussions of the design of the proton recoil spectrometers used at Argonne and of corrections for systematic measurement errors that are inherent in this form of neutron spectroscopy [2].…”

“…Collectively, these codes were referred to as the Proton Spectrum to Neutron Spectrum (PSNS) codes. The original PSNS codes performed several functions [2].…”

Neutron spectrum measurements for radiation protection purposes
