As currently configured by the Stanford Linear Accelerator Center (SLAC), the Next Linear Collider (NLC) is slated to use 6,000 PPM (periodic permanent magnet)-focused 75 MW klystrons. However, the PPM approach is not necessarily the lowest cost solution. This project will investigate a hybrid, periodic-solenoid approach. In this approach, the peak or average power of accelerator klystrons is increased by using low power, solenoid driven periodic beam focusing. The savings to NLC could be as much as $100M. Phase I will design a SPM (solenoid periodic magnet) beamstick that is compatible with the SLAC XL4 klystron geometry, conduct a computer evaluation of beam focusing, and fabricate a beamstick for evaluation by SLAC.
Commercial Applications and Other Benefits as described by the awardee: SPM focusing could be used in any application requiring large numbers of high-power klystrons (e.g.the NLC). The use of SPM technology could also be used to facilitate the laborious process of designing PPM klystrons.
