Abstract :
The paper presents the design of an X-band accelerating section for linearizing the longitudinal phase space in the Frascati Linac Coherent Light Source (SPARC). The structure, operating on the π standing wave mode, is a 9 cells structure fed by a central coupler and it has been designed to obtain a 42 MV/m accelerating gradient. The 2D profile has been determined using the electromagnetic codes Superfish and Oscar-2D while the coupler has been designed using HFSS. Beadpull measurements made on a copper prototype have been done and the results are illustrated and compared with the numerical ones. Mechanical details of the realized prototype and RF properties of the structure as a function of the assembly characteristics are also discussed.
