Ma. Lone et al., SENSITIVITY OF SELF-POWERED DETECTOR PROBES TO ELECTRON AND GAMMA-RAYFIELDS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 349(2-3), 1994, pp. 563-576
A self-powered detector (SPD) is a simple, passive device that consist
s of a coaxial probe with a metallic outer sleeve, a mineral oxide ins
ulating layer, and a metallic inner core. SPDs are used in nuclear rea
ctors to monitor neutron and gamma fields. Responses of SPDs to electr
ons and gamma-rays of various energies were investigated with Monte Ca
rlo simulations. Transmission filters were studied for the design of t
hreshold SPD probes used for on-line monitoring of the energy spectrum
of high-power industrial electron accelerator beams. Filters were als
o investigated for the enhancement of gamma-ray sensitivity of an SPD
placed in a mixed electron and gamma-ray field.
