Abstract
At the completion of the research and development effort a Li foil multi-wire proportional counter (MWPC) neutron detector with more than 625 cm^2 of active area will be included in a portable radiation detection system. The system is expected to have an intrinsic thermal neutron detection efficiency of 55% or greater and gamma-ray rejection ratio (GRR) of 1.0x10^-8 or better. A gamma-ray spectrometer for isotope identification will be included and offered as an optional attachment. Powering the gamma-ray and neutron detectors are portable electronics with reachback communication and GPS location capability. Reachback communication and GPS will allow the information obtained by the detectors to be sent back to a central monitoring station to allow a warfighter to be hands-free while maintaining interrogation capabilities. The main focus of the effort is the advancement of the Li foil MWPC neutron detector. Phase I includes feasibility studies of various areas for improvement on the MWPCs including reducing weight and increasing neutron sensitivity. The studies in Phase I will support the research efforts to be implemented in Phase II. Prototype systems in Phase I and Phase II will be tested against ANSI 42.53 and DNDO TCS backpack requirements.
