The Helium-3 shortage and the growing interest in neutron science constitute a driving factor developing new detection technologies. In this work, we report development of double-GEM detector prototype that uses $^{10}$B$_4$C layer as converter material. GEANT4 simulations were performed predicting an efficiency 3.14(10) %, agreeing within 2.7 $\sigma$ with experimental analytic efficiencies ob...
Time spectra of neutron and sonoluminescence emissions were measured in cavitation experiments with chilled deuterated acetone. Statistically significant neutron and gamma ray emissions were measured with a calibrated liquid-scintillation detector, and sonoluminescence emissions were measured with a photomultiplier tube. The neutron and sonoluminescence emissions were found to be time correlate...
The Gaerttner LINAC Center at RPI uses a 60 MeV electron linear accelerator to produce short pulses of neutrons with duration of 5-5000 ns. The main research thrust at the Center is nuclear data for nuclear reactors and criticality safety applications. The Center includes several setups for time-of-flight measurements including neutron transmission, capture and scattering detectors, and a lead ...
The GEM-based neutron detector has flourished in the past decade. However almost all detectors work flow-gas mode, and long-term performances of may be unstable due to dynamic changes atmospheric pressure ambient temperature. In this paper, a sealed ceramic was developed at China Spallation Neutron Source (CSNS) its sensitive area 100 mm * mm. characterizations were presented discussed, which i...
