Investigation of Slotted Slow-Wave Structures for Stochastic Cooling

T. Lau1, T. Weiland1, and F. Nolden2 1Technische Universität Darmstadt, Institut für Theorie Elektromagnetischer Felder (TEMF); 2GSI, Darmstadt, Germany In the new international project FAIR at GSI stochastic cooling of secondary particles will be an important technical element. Therefore, an investigation of kicker and pickup slow-wave structures similar to the devices investigated by Faltin [1] and McGinnis [2] have been performed with the help of the simulation package CST PARTICLE STUDIOTM [3]. Slow-wave structures as pickups are more sensitive in the region of a few Gigahertz than broad band loops. Especially, they don’t need binary combiner boards and thus prevent the associated problems with them. The working
