Accurate neutron detection can be important for nuclear forensics, safeguards, and nuclear security applications. Organic scintillation detectors are used widely due to their resilience, rapid timing characteristics, and their dual sensitivity to both gamma and fast neutron events. Pulse-shape discrimination (PSD) is often used to separate gamma and neutron events as part of the analysis of...
In various critical applications, the accurate estimation of physical parameters is a necessity for ensuring public safety and effective decision-making. One such critical application where these considerations come into play is source term estimation (STE) in the context of hazardous material releases. The urgency for rapid and precise STE is accentuated by the growing risks of hazardous...
We present a summary of a commercial off the shelf data acquisition project to demonstrate the ability to use a Raspberry Pi as a data acquisition system for a multi channel readout of sensors. The system realised was capable of reading out with a 150ns sampling rate and had a 16 channel capability (expandable to 32 channels) with a touch screen interface. This could be used for radiation...
Detection of nuclear materials remains a matter of utmost importance due to potential security issues. Current detection techniques for neutrons and gammas involve using a combination of a 3He proportional counter, which allows for detection of thermal neutrons, along with a plastic scintillator, which allows for detection of gammas. This in itself creates issues as 3He is a rare and expensive...
Conventional nuclear well-logging detectors employ a neutron source downhole in parallel with a detector tool to monitor interactions of radiation with the surrounding rocks. Chemical radioisotope source replacement is desirable to reduce the number of high activity AmBe and Cf-252 sources in circulation, and replace them with electrical pulsed sources. Deuterium-Tritium (D-T) sources offer...
