Magnet Main differences between proton only and multi-particle Yokes/flux returns in 1 piece No more compensation coil No more pole extension (He++ focalisation) Optimisation of pole thickness and profile Gap increasing (30 mm ->40 mm) Protect, Enhance and Save Lives - 14 - Why? Assembly optimised Better vacuum level Reduce power consumption (main coil + harmonic coils) Improve vacuum pumping

RF system Cyclone 70 Xp - ~30 MHz in H 2 for protons, H 4 for M/Q=2 Different stem configurations have been tested in order to find the best compromise between mechanical/RF/beam parameters.
