Abstract
161 A 34 GHzHigh-Power Micro-Pulse Klystron--FM Technologies, Inc., 10529-B Braddock Road, Fairfax, VA 22032-2236; (703) 425-5111 Dr. Frederick M. Mako, Principal Investigator Dr. Frederick M. Mako, Business Official DOE Grant No. DE-FG02-97ER82374 Amount: $75,000 High-current pulses of electrons are widely used in injector systems for electron accelerators, such as industrial linacs, as well as high-energy accelerators for linear colliders. Current methods of forming bunches of electrons are rather complex, cumbersome, expensive, and have very definite limits on performance. To overcome these problems, this project will concentrate on a new concept for a 34.2-gigahertz, high-power multiplying klystron system called a micro-pulse klystron. The micro-pulse gun forms the input radio-frequency cavity, and for every period of the radiofrequency period, it products a very short bunch. Its desirable characteristics are that it appears to be capable of producing high current densities and short pulses. The bunch pulse width can be adjusted from 1.5-10 percent of the radiofrequency period depending on the radio-frequency voltage level and cavity gap spacing. A point design was developed based on 11.4 gigahertz input to produce 147 megawatt output at 34.2 gigahertz with 65 percent system efficiency. Mode locking without mode competition is achievable in the output cavity. Phase I is aimed at a detailed analysis to establish credible estimates of radiofrequency power requirements, pulse length, emittance, efficiency, gain and other key parameters. Commercial Applications and Other Benefits as described by the awardee: If successful, this micro-pulse klystron should provide a high-power, high-frequency source suitable for high-energy accelerators for linear colliders, free electron lasers, medical and industrial radio-frequency linacs, super-power nanosecond radar, and accelerator test facilities. Of particular interest are 34.2 gigahertz radiofrequency generators for future linear colliders.
