INSTALLATION AND TESTS OF THE X-BAND POWER PLANT FOR THE FERMI @ ELETTRA PROJECT

FERMI@Elettra, the fourth generation light source facility at the Elettra Laboratory in Trieste, Italy, foresees an X-band accelerating section downstream the first bunch compressor to linearize the beam longitudinal phase space. The RF power for the structure is produced by a SLAC XL5 klystron, a scaled version of the XL4 tube, operating at the European frequency of 11.992 GHz. The 50 Hz klystron modulator is based on a standard pulse forming network (PFN) design, with a thyratron and pulse transformer, with which Elettra has extensive experience. We report on the installation and tests of the first high power RF station.
