High-pressure Helium-3 Scintillation Position-sensitive Detector of Thermal Neutrons
The objective of this study is to demonstrate the feasibility of constructing a compact neutron detector that is sensitive to thermal and epithermal neutrons and has high rejection efficiency relative to gamma-ray background. A two-channel high-pressure He scintillation detector is considered for the detection of neutrons in coincidence mode. The detector consists of two large avalanche photodi...
متن کاملA Position-Sensitive Ionization Chamber for Thermal Neutrons
A position-sensitive neutron detector based on He is being developed for a national crystal backscattering spectrometer (CBS) at a pulsed neutron source. It comprises a single gas volume, of constant depth, in the form of an annulus that is also part of a truncated cone. Charge from each event is collected on one or two anode strips, out of a total 336 around the annulus, yielding an angular re...
متن کاملDevelopment and performance of a position-sensitive proportional avalanche counter tracking system
Most of our current understanding in nuclear physics has come from using stable targets and beams. Stable nuclei represent only a small fraction of the total nuclei that can exist, but do not exhibit many of the exotic proprieties seen in nuclei far from stability, such as halos [1]. The ability to study unstable nuclei has opened up a vast new range of physics to be explored. The decay of thes...
متن کاملSCINTILLATION PROPORTIONAL Xe COUNTER WITH WLS FIBER READOUT FOR LOW-ENERGY X-RAYS
A gas Xe based scintillation proportional counter with cylindrical geometry and wavelength shifting (WLS) fiber readout for X-rays of energy 0.5 − 100 keV is proposed. With such a design large sizes and sensitive area of the counter with a fairly well uniformity is possible. The counter could be used for ”dark matter” search and neutrino magnetic moment measurement and for detection of small am...
متن کاملActivation Measurements for Thermal Neutrons
The neutron energy spectrum from the atomic bomb consisted of a range of energies from thermal to fast neutrons. Fast neutrons contribute a larger dose to the human body than lowenergy neutrons per unit flux. The evaluation of the fast neutron component has been performed based on analyses of P (>3 MeV) activity measured immediately after the Hiroshima bomb and Ni (>2 MeV), which has a much lon...
