Abstract41299 November 19, 1996 FM Technologies, Inc. In the Relativistic Klystron Two-Beam Accelerator, which is currently under development, power from a low-energy, high-current, bunched beam is converted to micro-waves via the klystron mechanism and used to provide power for a high-energy linac, specifically a future Next Linear Collider upgrade to l.0 TeV. This project will develop an induction accelerating cavity assembly for the low-energy accelerator. The accelerating cavity will be integrated with the driving modulators currently under development; thousands of these units would be required for a full-scale collider. In Phase I, a preliminary design will be completed which will consider the cost, efficiency, and technological feasibility of the proposed design. The design will address techniques to minimize high-voltage breakdown, azimuthal currents, high order resonances, and beam-breakup instabilities. Phase II will design, develop, and fabricate individual parts of a prototype induction cavity assembly. These parts will be assembled and tested at Lawrence Berkeley National Laboratory. Commercial Applications and Other Benefits as described by the awardee: Successful development of the accelerating cavity, integrated with the driving modulator, for the two-beam accelerator will enable the Department of Energy to assess this potentially promising method in a far more definitive manner than is available from conceptual studies. Other applications include more powerful electron linacs for industry and medicine, and high-power ion linacs for pulsed spallation neutron sources and materials irradiation.
