In order to obtain high luminosity and energy efficiency in future linear col-liders, it is desirable to accelerate a train of closely spaced bunches on each rf pulse of the machine. There can be severe multibunch beam break-up in such a collider unless some means of strongly suppressing the transverse wakefield is incorporated into the design of the(More)
The linacs proposed for the Next Linear Collider (NLC) and Japanese Linear Col-lider (JLC) would contain several thousand X-Band accelerator structures that would operate at a loaded gradient of 50 MV/m. An extensive experimental and theoretical program is underway at SLAC, FNAL and KEK to develop structures that reliably operate at this gradient. The(More)
Almost all the electricity currently produced in the UK is generated as part of a centralised power system designed around large fossil fuel or nuclear power stations. This power system is robust and reliable but the efficiency of power generation is low, resulting in large quantities of waste heat. The principal aim of this paper is to investigate an(More)

The next generation of linear colliders requires peak power sourcesof-over 200 MW per meter at frequencies above 10 GHz at pulse widths of less than 100 nsec. Several power sources are under active development, including a conventional klystron with RF pulse compression, a relativistic klystron (RK) and a crossed-field amplifier. Power from one of these has(More)
Relativistic klystrons are being developed as a power source for high gradient accelerator applications which include large linear electron-positron colliders, compact accelerators, and FEL sources. We have attained 200MW peak power 'at 11.4 GHz from a relativistic klystron, and 140MV/m longitudinal gradient in a short 11.4 GHz accelerator section. We(More)
