Demonstration of an accelerating gradient of 100 MV/m at a breakdown rate of 10-7 is one of
the key feasibility issues of the CLIC study. A high power RF test program both at X-band
(SLAC and KEK) and 30 GHz (CERN) is under way to develop accelerating structures which
reach this performance. The centrepiece of the testing program is the nominal CLIC
accelerating structure [1], but also includes structures with different RF parameters, with and
without wakefield damping waveguides and made with different fabrication technologies …
