Description

Breakdowns in high-gradient RF cavities, as used e.g. in the CLIC project, are a major limit of the cavity performance. A new approach to explain these breakdowns based on a locally varying work function has been investigated at the CERN photoemission laboratory. The response of copper photocathodes to different wave lengths has been measured and compared with the data measured in a similar facility. An explanation of the difference between the two data sets will be proposed and further measurement steps outlined.
