Upgrade of the SPS Ion Injection System

As part of the LHC Injectors Upgrade Project (LIU) the injection system into the SPS will be upgraded for the use with ions. The changes will include the addition of a Pulse Forming Line parallel to the existing PFN to power the kicker magnets MKP-S. With the PFL a reduced magnetic field rise time of 100 ns should be reached. The missing deflection strength will be given by two new septum magnets MSI-V, to be installed between the existing septum MSI and the kickers MKP-S. A dedicated ion dump will be installed downstream of the injection elements. The parameter lists of the elements and studies concerning emittance blow-up coming from the injection system are presented. The feasibility of the 100 ns kicker rise time and the small ripple of the septum power converter are presented. Material studies of the ion dump are presented together with the radiation impact.
