Note:
1.1.1: The propose of this project is to investigate the feasibility of obtaining high efficiency BN fast neutron detectors by stacking up multiple BN blocks of 1 mm in thickness. The well-established HVPE semi-bulk crystal growth method will be adopted and further developed to produce BN wafers up to 1 mm in thickness. For commercial adoption of BN fast neutron detectors, the initial unit price could be an important factor. The proposed device architecture will ensure sufficient detection efficiencies for both thermal neutrons and fast neutrons even if the detectors are fabricated from natural boron source. The use of natural BN crystals will significantly reduce the production cost of BN fast neutron detectors than those based on boron-10 enriched BN crystals.
