EXPERIENCE OPERATING AN X-BAND HIGH-POWER TEST STAND AT CERN

CERN has constructed and is operating a klystron- based X-band test stand, called Xbox-1, dedicated to the high-gradient testing of prototype accelerating structures for CLIC and other applications such as FELs. The test stand has now been in operation for a year and significant progress has been made in understanding the system, improving its reliability, upgrading hardware and implementing automatic algorithms for conditioning the accelerating structures.
