(a) Schematic of the parameterised slab model used for the \(^3\)He detector optimisations. 50 tubes were used for these simulations, the additional 48 tubes present in the centre of the model have been omitted for clarity. Parameters optimised included: 1. the spacing between detectors, 2. the air void thickness around the detector, 3. the outer reflector box thickness and 4. the air gap between the reflector and Pb producer. Parameters were optimised in order of predicted impact each would have on the overall detection efficiency. (b) Cutaway isometric (to scale) of the \(^3\)He optimised model with key dimensions as indicated. (c) Vertical cross section (to scale) of \(^3\)He optimised model with key dimensions as indicated.
