Beam-beam kicker for superfast bunch handling

A novel method of a very fast kicker based on beam-beam forces is suggested. The method assumes impact of a high pulse current, low energy beam on the bunches which circulate in a storage ring. The kicker allows to handle separately the bunches spaced by only a few tens of centimeters. The article is devoted to the technical consideration of the kicker construction, its ultimate possibilities and the choice of itsʹ parameters. Two schemes with head-on and perpendicular crossing are considered. The possible applications of the beam-beam kicker as an injector/extractor for the TESLA damping ring and as a diagnostic tool at multibunch storage rings are discussed.
