Abstract50321-98-I A High-Brightness, X-Band Photoelectron Linac--Duly Research, Inc., 1912 MacArthur Street, Rancho Palos Verdes, CA 90275-1111; (310) 548-7123 Dr. David U.L. Yu, Principal Investigator Dr. David U.L. Yu, Business Official DOE Grant No. DE-FG03-98ER82566 Amount: $75,000 The goal of this project is to develop an economical, subpicosecond bunched photoelectron linac with the highest brightness ever. The high brightness is made possible by accelerating photo-electrons produced by a short pulse laser at an X-band (8-12 GHz) rf frequency. It will employ a novel accelerator design called the plane wave transformer in which cells are strongly coupled, easing manufacturing tolerances and saving cost. Phase I work will include design of the X-band accelerating structure and the focusing solenoids using numerical simulations and cold test models. Beam dynamics simulations will be done to insure achievement of a low-emittance beam. Engineering design of the rf power system and the laser system will also be made in Phase I. Commercial Applications and Other Benefits as described by the awardee: Ultra-short photoelectron bunches are useful in future linear colliders and in compact electron injectors for advanced light sources such as free electron lasers, synchrotrons and Compton backscattered X-rays, with a myriad of uses in research, industry and medicine. _
