Abstract

Instead of using a gas which reacts directly to neutron bombardment, one set of cartesian electrodes if of material which emits ionising particles when exposed to neutron radiation and the pairs of electrodes forming the individual cells have a p.d. across them such that each cell is a direct charge detector, or the whole of one wall may be so coated, the cathodes being conductive strips on the opposite wall and the anodes being within the cell between the walls. The gas filling used is 95% A and 5% CH4 or CO2. The ionising radiation emissive material is B enriched with B-10, or Li enriched with Li-6- or U enriched with Li-6.
