RF design of a crab cavity (2/3, 11.9942 GHz) for
the Compact Linear Collide (CLIC) is presented. As part
of the UK-CLIC collaboration, CERN is building two
copper prototypes, designed by Lancaster University /
Cockcroft Institute. The first prototype to be made will
be a 12 cell undamped cavity and the second will be
waveguide damped cavity. The RF test at CERN will help
characterisation of the dipole mode with X-band RF
pulses of 15 MW peak power and pulse length of ~242 ns.
Since the cavity frequency and phase advance per cell are
identical to those of the CLIC main linac, the first
prototype could exploit CERN’s X-band cavity
characterisation facilities. A fully damped cavity will be
required for the actual machine in order to meet the
luminosity specs. The damped prototype will use an
identical coupler type as the undamped one, but the cells
will have damping waveguides with / without d |
