  Lithium 8 is a short lived beta emitter producing a high energy anti-neutrino, which is very suitable for making several measurements of fundamental quantities. It is proposed to produce Lithium 8 with a commercially available 60 MeV cyclotron using protons or alpha particles on a Beryllium 9 target. We have used the GEANT4 program to model these processes, and calculate the antineutrino fluxes that could be obtained in a practical system. We also calculate the production of undesirable contaminants such as Boron 8, and show that these can be reduced to a very low level.

  DAEδALUS, the Decay At-rest Experiment for δCP At the Laboratory for Underground Science will look for evidence of CP-violation in the neutrino sector, which may explain the matter/antimatter asymmetry in our universe. It will make precision measurements of oscillations of anti-muon neutrinos to anti-electron neutrinos using multiple neutrino sources created by low-cost compact cyclotrons. DAEδALUS will utilize a decay-at-rest neutrino beam produced by 800 MeV protons impacting a graphite target. Two well established Monte Carlo codes, MARS and GEANT4, have been used to optimize the design and the performance of the target. A benchmarking of the results obtained with these codes is also presented in this paper.
