Description
ISIS-II, the proposed successor to the UK’s pulsed neutron and muon source, has been baselined with two newly-designed spallation targets [1]: An 800 kW, high-brightness stationary target (TS-II). And a 1.6 MW, high-resolution rotating target (TS-I).
Research highlighted decay heat as the key limiting factor for the former and rotational inertia or complexity for the latter. This work showcases the details of the optimisation procedures applied to various aspects of the targets designs, including selecting the number of target plates, target segments and cooling conditions. A combination of numerical models and theoretical calculations were employed to assure design reliability and to compare with international institutions.
