Progress with the CLIC Transfer Structures(CTS)

It is foreseen that the transfer structures (CTS) of the drive linac will produce 40 MW, 11.4 ns, 30 GHz rf power pulses for acceleration purposes in the CLIC main linac. At present a real size Cu 30 GHz CTS has been brazed, vacuum tested and and measured RF-wise with the beam simulating wire method. Furthermore a simplified version is ready for power testing with an MIT 33 GHz FEL power source.
