We study the performance of gamma = 100 Beta-Beam setups based on the decays of 8B and 8Li as a function of the achievable production fluxes and compare them with the standard setups based on 18Ne and 6He decays.
- For the standard setup we also investigate the physics potential for reduced 18Ne fluxes, since it seems experimentally challenging to achieve the baseline numbers.
- We find that, contrary to the standard setup, setups based in 8B and 8Li can be sensitive to the mass hierarchy down to values of sin^2 2theta_{13} > 10^-2 by themselves, due to the stronger matter effects granted by the higher energy of the neutrinos.
- On the other hand, the longer baseline required for neutrinos to oscillate at these higher energies reduces the statistics at the detector and fluxes around three times larger are required to reach the sensitivity to theta_{13} and CP violation for the smallest values of sin^2 2theta_{13} that the standard setup provides.
