Abstract:
A β\beta-beam with maximum γ=150\gamma=150 (for \helio ions) or γ=250\gamma=250 (for \neon) could be achieved at the CERN-SPS. We study the sensitivity to θ13\theta_{13} and δ\delta of such a beam as function of γ\gamma, optimizing with the baseline constrained to CERN-Frejus (130 km), and also with simultaneous variation of the baseline. These results are compared to the {\it standard} scenario previously considered, with lower γ=60/100\gamma=60/100, and also with a higher γ350\gamma\sim 350 option that requires a more powerful accelerator. Although higher γ\gamma is better, loss of sensitivity to θ13\theta _{13} and δ\delta is most pronounced for γ\gamma below 100.
