Abstract

Boron-Lined neutron detector may be a substitute of ³He proportional counter in the field of thermal neutron detection. We present in this paper the simulation results of the detection efficiency and energy response of the boron-lined detector. Thickness of natural or enriched B₄C, which is used as the neutron converter to emit charged particles to form signals in proportional gas, is researched to achieve the optimized efficiency for a single detector or the whole detector array. The relationships between the rate of spurious events caused by scattering and row number or thickness of the substrate of the detectors are also researched.
