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...

The MeV region of antineutrino energy is special interest for physics research and monitoring nuclear nonproliferation. Whereas liquid scintillation detectors are typically used to detect the Inverse Beta Decay (IBD), it has recently been proposed with a liquid-organic Time Projection Chamber, which could allow full reconstruction particle tracks IBD final state. We present first comprehensive ...
