A possible RF System for CERN RCS

As part of the LHC Injectors Upgrade (LIU) program at CERN the possibility of replacing the PSB with a new Rapid Cycling Synchrotron (RCS) is considered1. The requirements in terms of accelerating voltage (60 kV), frequency range (1.3 MHz – 9.6 MHz) and available space (4.7 m) make the RF system development quite challenging. The improved loss characteristics of the new FINEMET® type (FT3L) combined with a filter-like topology, allows achieving all the requirements. This paper describes the design of such a RF system
