High power test results of the SPARC C-band accelerating structures

The energy upgrade of the SPARC photo-injector at LNF-INFN (Italy) from 180 to more than 240 MeV will be carried out by replacing a low gradient S-Band accelerating structure with two C-band structures. The structures are Traveling Wave (TW) and Constant Impedance (CI), with symmetric axial input co...

Sumario:The energy upgrade of the SPARC photo-injector at LNF-INFN (Italy) from 180 to more than 240 MeV will be carried out by replacing a low gradient S-Band accelerating structure with two C-band structures. The structures are Traveling Wave (TW) and Constant Impedance (CI), with symmetric axial input couplers and have been optimized to work with a SLED RF input pulse. In this paper we present the results of the low and high power RF tests on the two fabricated structures that shown the feasibility of the operation at accelerating gradients larger than 35 MV/m.
