Preliminary RF design of an X-band linac for the EuPRAXIA@SPARC_LAB project : arXiv

Abstract In the framework of the upgrade of the SPARC_LAB facility at INFN-LNF (Frascati, Italy), named EuPRAXIA@SPARC_LAB, a high gradient linac is foreseen. One of the most suitable options is to realize it in X-band. A preliminary design study of both accelerating structures and power distribution system has been performed. It is based on 0.5 m long traveling wave (TW) accelerating structures operating in the 2 π ∕ 3 mode and fed by klystrons and pulse compressor systems. The main parameters of the structures and linac are presented with the basic RF linac layout.
