In-Core Neutron Flux Instrumentation
IEEE Transactions on Nuclear Science, 1965A survey of the new work in the neutron monitoring of a nuclear power reactor is presented. The sensors have been moved into the reactor and the three modes of measurement necessary to cover the ten decades of the in-core neutron range from startup to rated power are described. The system specifications and life performance data are reviewed.

A Channel for Neutron Flux Measurement
Instruments and Experimental Techniques, 2002The design principles of a channel for measuring fluxes of thermal neutrons in a nuclear-reactor control and protection system are considered. The channel consists of a fission chamber, a set of boron-containing gas-filled ionization chambers, and an electronic unit that ensures a counting rate of fission pulses of up to ∼1 × 106 s–1.

Small Effects and Neutron Flux
Journal of Neutron Research, 1996The conversion of modern research reactor facilities or designs with high flux-to-power ratios (small cores) from high-enriched uranium (93%, which is weapons grade) to low-enriched uranium (less than 20% 235 U) leads to a flux loss of up to 70% [l, 2].

On the flux of neutrons from flares
Solar Physics, 1971Under the assumption that white-light flares are caused by energetic particles penetrating into the photosphere (Svestka, 1970a; Najita and Orrall, 1970) the known number of protons needed for the white-light emission is used to obtain an estimate of the production of neutrons occurring at the same time.
