Phys. Rev. ST Accel. Beams 10, 042003 (2007) [8 pages]High-efficiency absorber for damping transverse wakefields
A. Novokhatski *, J. Seeman, and S. Weathersby Received 5 February 2007; published 26 April 2007 Transverse wakefields generated by intense beams may propagate long distances in a vacuum chamber and dissipate power in different shielded elements such as bellows, vacuum valves, or vacuum pumps. Induced heating in these elements may be high enough to deteriorate vacuum conditions. We have developed a broadband water-cooled bellows absorber to capture and damp these harmful transverse fields without impacting the longitudinal beam impedance. Experimental results at the PEP-II SLAC B-factory demonstrate a high efficiency for this device. This absorber may be useful in super B-factories, the International Linear Collider, the Large Hadron Collider, or synchrotron light sources. ©2007 The American Physical Society
