The new 400 Hz 120 MV/m photoinjector for CLARA will soon be conditioned. An automated RF conditioning program has been developed to perform the conditioning repeatably and with the minimum possible damage to the cavity. The program has been tested when re-conditioning on the current photoinjector, as well as on the first travelling wave linac. Conditioning method;differences for travelling...
At the high-gradient X-band test facility at CERN, prototype accelerating structures for the Compact Linear Collider (CLIC) are tested at high powers of up to 50 MW to achieve accelerating gradients of over 100 MV/m and peak surface electric fields of over 220 MV/m, and are conditioned to reach the highest possible gradient at low breakdown rate. The setup of the test stands will be presented,...
In order to further investigate field emission and vacuum arcs which limit the performance of the high gradient accelerating structures. New ways of measuring the properties of the plasma formed due to these processes are being developed. A novel experiment based on a microwave probe is discussed. The HOM damping waveguides of a TD24 CLIC structure are used to insert a low power RF signal,...
