Alpha Background in Multi-Grid Neutron Detectors
A. Backis, C. -C. Lai, J. R. M. Annand +4
Alpha emission from actinide impurities in Al is a source of background counting rate in Multi-Grid type detectors of thermal neutrons. The alpha emission rates from samples of rad…
The Application of VMM3A Readout for Multi-Grid Neutron Detectors
A. Backis, F. Piscitelli, D. Pfeiffer +6
The T-REX neutron spectrometer at the European Spallation Source will use Multi-Grid Technology, which is a voxelised proportional counter relying on\mathrm{^{10}B_{4}C} coatings t…
Technique for the measurement of intrinsic pulse-shape discrimination for organic scintillators using tagged neutrons
N. Mauritzson, K. G. Fissum, J. R. M. Annand +10
Fast-neutron/gamma-ray pulse-shape discrimination has been performed for the organic liquid scintillators NE 213A and EJ 305 using a time-of-flight based neutron-tagging technique…
Light-yield response of liquid scintillators using 2--6 MeV tagged neutrons
N. Mauritzson, K. G. Fissum, J. R. M. Annand +10
Knowledge of the neutron light-yield response is crucial to the understanding of scintillator-based neutron detectors. In this work, neutrons from 2--6 MeV have been used to study…
Neutron Interaction Properties of Structural Materials for Multi-Grid Neutron Detectors
A. Backis, C. -C. Lai, M. Aouane +5
The T-REX neutron time-of-flight spectrometer at the European Spallation Source will use Multi-Grid Technology, which relies on thin B4C coatings on the Al blades of the grids to d…
Time- and energy-resolved effects in the boron-10 based Multi-Grid and helium-3 based thermal neutron detectors
A. Backis, A. Khaplanov, R. Al Jebali +33
The boron-10 based Multi-Grid detector is being developed as an alternative to helium-3 based neutron detectors. At the European Spallation Source, the detector will be used for ti…
