Transfer Line for ultra short bunches from FLUTE to cSTART — •Jens Schäfer2, Bastian Härer1, Alexander Papash1, and Anke-Susanne Müller1,2 — 1IBPT, KIT, Karlsruhe, Germany — 2LAS, KIT, Karlsruhe, Germany
The FLUTE test experiment at KIT produces 50 MeV electron bunches with ultra short bunch lengths of only a few femtoseconds to create coherent THz radiation. These bunches will be transferred to the high acceptance storage ring cSTART which will be installed right above FLUTE. The low energy loss due to synchrotron radiation at 50 MeV results in a damping time of 20 s which makes cSTART an excellent tool to investigate short bunches in a non-equilibrium regime. This presentation adresses the status of the transfer line from FLUTE to cSTART which should maintain the ultra short bunch length and provide additional compression if needed. The layout of FLUTE and cSTART requires deflection of the beam in both transversal planes with only limited space. At the insertion point, the beam parameters have to be matched to the optics of cSTART with a given flexibility, taking non-linear effects into account. In addition cSTART serves as a test area for a LWFA as full-energy injector, therefore the transfer line has to allow modifications of the energy spread for preliminary studies.
