50MW X-band High Efficiency Klystron has been developed in CERN for CLIC Klystron driven scheme, as essential upgrade of its commercial counterpart. In this presentation, both the home-made simulation tool and specific design procedure will be elaborated. By taking the advantage of the updated coupling-cell module and optimization module implemented in KlyC, the retrofit Klystron could deliver...
Abstract: We provide a system description of the LANL CERF-NM test stand, and discuss the operation and initial conditioning efforts. The specified klystron peak power of 50MW, operating with a 1µs pulse-width at a pulse repetition rate of 100 Hz (5kW average power) was achieved working into a matched water-cooled waveguide load.

The RF power chain – including modulators and RF amplifiers themselves – is a major driver of capital and operational costs for any next-generation accelerator facility. For the current state of the art, RF power costs are likely prohibitive, and an order of magnitude improvement (in terms of $/peak kW) is needed. To this end, SLAC is developing a widely scalable RF source and modulator...
We present recent experimental results generating 510 MW of power at 11.7 GHz using a metallic metamaterial-based power extractor for use in structure-based wakefield acceleration (SWFA). SWFA is a novel acceleration scheme in which high-charge electron bunches are passed through a power extractor structure to produce a high-intensity wakefield. The resulting wakefield can either be used to...
