Optimisation Studies of a High Intensity Electron Antineutrino Source

ISODAR (Isotopes-Decay-At-Rest) is a novel, high intensity source of electron antineutrinos produced by the decay of Li-8 isotopes, which aims for searches for physics beyond the standard model. The Li-8 isotopes are produced in the inelastic interactions of low energy protons or deuterons with a Beryllium target. In addition the Li-8 is produced in the surrounding materials by secondary neutrons. This paper focuses on the optimisation of the base design target, moderator and reflector.
