B-Lined Proportional Counters to Traditional Neutron Counting Applications in International Safeguards
Many neutron-detection techniques are under consideration as potential replacements for 3 He gas-filled proportional tubes, which are widely used in international nuclear safeguards applications. The traditional 10 B-lined proportional tube is a commercial off-the-shelf (COTS) technology for neutron detection that predates the development of 3 He detectors. There is also a long history of its u...
متن کاملModelling moderated proportional neutron counters using the Geant4 toolkit and the application to detection of fast neutron burst
The modelling with the Geant4 toolkit of moderated 3He-filled proportional neutron counters is studied. The energy deposition spectra by the neutron capture products in the gas counter is compared with experimental results. On the other hand, efficiency calculation for polyethylene moderated proportional counters are compared with experimental and MCNPX results.Finally, the application of the G...
متن کاملProportional Counters as Low Energy Photon Detectors
We have investigated the response of an argon-methane proportional counter to monochromatic X-rays in the range 99-277 eV . The apparent nonlinearities in mean pulse height as a function of photon energy and the detailed shape of the pulse height distribution for each energy can be predicted quite precisely using the extensive atomic data available for argon. Based on this understanding, we pro...
متن کاملFull simulation of the Sudbury Neutrino Observatory proportional counters
The third phase of the Sudbury Neutrino Observatory (SNO) experiment added an array of 3He proportional counters to the detector. The purpose of this neutral-current detection (NCD) array was to observe neutrons resulting from neutral-current solar-neutrino–deuteron interactions. We have developed a detailed simulation of current pulses from NCD array proportional counters, from the primary neu...
متن کاملGas Scintillation Proportional Counters for High-Energy X-ray Astronomy
A focal plane array of high-pressure gas scintillation proportional counters (GSPC) for a balloon-borne hard-x-ray telescope is under development at the Marshall Space Flight Center. These detectors each have an active area of ~ 20 cm, and are filled with a high pressure (10 Pa) xenon-helium mixture. Imaging is via crossed-grid position-sensitive phototubes sensitive in the UV region. The perfo...
