Radiation Hardness of PS Magnets during β-beam Operation*

The EURISOL β-beam project addresses the design of accelerators for the production of high flux neutrino beams. With the aim to exploit the existing PS and SPS synchrotrons at CERN, it is proposed to create neutrinos and antineutrinos from high intensity radioactive beams. Boosted to high relativistic energies in the SPS and then injected into an elongated storage ring, narrow cones of neutrinos are produced. The He and F isotopes are intended to be produced by the planned EURISOL facility. The present candidates are He Li+β+ν and Ne F+β+ν which would achieve a reasonable decay rate at γ=100 in the decay ring.
