Description

'To accelerate as no man has before'

The CLIC-study is aiming for an accelerating gradient of 150 MV/m at a pulse length of 130 ns using 30 GHz traveling-wave accelerating structures. This year a series of conceptually new structures have been designed taking into account the lessons learned in the past and tested with high power in CTF II. Features are a new RF design and new materials like Tungsten and Molybdenum with the potential to withstand breakdowns.
All new structures exceeded substantially previous achieved accelerating gradients for CLIC prototype structures. A tungsten-iris structure reached a peak-accelerating gradient of 150 MV/m at a pulse length of 16 ns, which is likely a new record in conventional RF based accelerating structures. Concepts and results of these structures will be presented concluding this year's final run auf CTF II.
