A β-beam with maximum (for 6He ions) or (for 18Ne) could be achieved at the CERN-SPS. We study the sensitivity to and δ of such a beam as function of γ, optimizing with the baseline constrained to CERN–Frejus (130 km), and also with simultaneous variation of the baseline, for a fixed ion flux. These results are compared to the standard scenario previously considered, with lower , and also with a higher option that requires a more powerful accelerator. We conclude that the sensitivity to CP violation and increases significantly with γ if the baseline is increased proportionally, while for the CERN–Frejus scenario the dependence on γ is mild provided γ is above 100.
