A position-sensitive wire-strip thermal- and cold-neutron detector with a boron converter

A position-sensitive wire-strip detector for thermal and cold neutrons is developed. The neutron converter is a 5-μm layer of 10B. Secondary α-particles are captured in a 1-mm gap of 73%Ar + 25% CO2 + 2% SF6 gas mixture at atmospheric pressure. The gas gain is ensured by an array of 20-μm wires of gold-coated tungsten.
