  A new klystron based x-band rf power source working at 11.994GHz has been installed and commissioned at CERN in collaboration with CEA Saclay and SLAC for CLIC accelerating structure tests. The system comprises a solid state high voltage modulator, an XL5 klystron developed by SLAC, a cavity based SLED type pulse compressor, the necessary low level rf system including rf diagnostics and interlocks and the surrounding vacuum, cooling and controls infrastructure. The klystron can produce up to 50MW rf pulses of 1500ns pulse width and 50Hz repetition rate. After pulse compression, up to 100MW of rf power at 250ns pulse with are available in the structure test bunker. This paper describes in more detail this setup and the results of the commissioning which was necessary to arrive at the mentioned performance.
