A novel two-beam accelerator (twobetron)
- Intense Energy Beam Interaction Laboratory, Department of Nuclear Engineering, University of Michigan, Ann Arbor, Michigan 48109-2104 (United States)
A new configuration is analyzed wherein a low current beam is accelerated to high energies (10{close_quote}s of amps, 10{close_quote}s of MeV) by a driver beam of high current and low energy (a few kiloamps, {much_gt}1 MeV). The annular driver beam excites the {ital TM}{sub 020} cavity mode of an accelerating structure which transfers its rf power to the on-axis secondary beam. Systematic variation of the driver beam radius provides the secondary beam with phase focusing and adjustable acceleration gradient. A proof-of-principle experiment is suggested. Various issues, such as the scaling laws, transverse and longitudinal instabilities, rf coupling among cavities, etc., are examined. {copyright} 1995 {ital American Institute of PHysics}.
