Title: Injection and extraction for SUSE

Abstract

The injection onto the first cyclotron orbit differs essentially from injection schemes for normal conducting sector cyclotrons because of two reasons: the central region is occupied by the RF-cavities, and the stray field between the sectors is strongly nonscaling with the mean field level. An appropriate injection and extraction system was developed using a series of superconducting channel magnets which cause practically no field perturbation outside and produce field levels of several Tesla inside. These magnets have a closed structure - like a shielding Faraday box in the electrostatic analogon. Therefore the injection path is below the median plane in the region of the circulating orbits. The accelerated beam will be extracted with an electrostatic septum (10 MV/m). Single turn extraction is achieved primarily by the acceleration voltage of 2 MV/turn, giving a turn-separation of 2.5 mm for 300 MeV/u and Q/A = 0.5. The separation may be increased by coherent betatron-oscillations.
