Continued progress in high energy physics demands a new generation of linear collider, which in turn requires new high-power, high-efficiency radio frequency (rf) sources. One of the most attractive candidates for this role is the magnicon are needed microwave amplifier with circular deflection of an electron beam. In order to realize optimum performance, detailed numerical design simulations of the magnicon are needed that take into account beam space charge. This project will develop sophisticated computer software to simulate the 3-D electron beam dynamics in magnicons, including realistic rf field distributions, static magnetic field profiles, and beam space charge. The result is expected to be a powerful tool for evaluating the performance of candidate magnicon amplifier designs, in both time-dependent and steady-state operation. The software will also be useful for design of gyroklystrons and gyroharmonic converters. During Phase I, a 3-D Poisson solver will be developed, based on a second-order finite element method, together with a generator of a 3-D curvilinear mesh. A particle pusher routine and an economic space charge model also will be developed. Preliminary physical simulations to show the influence of beam space charge on the performance of a high-power magnicon will be demonstrated.
Commercial Applications and Other Benefits as described by the awardee: In a future linear collider, several thousand high-power, high-efficiency microwave amplifiers will be required. If the magnicon were adopted for such an application, it would represent a business opportunity with a potential in the range of $200 million. Additional markets for magnicon amplfiers could include rf sources for the accelerator in a fourth-generation synchrotron radiation light source, as well as numerous related commercial uses.
