Basic investigations of a bipolar kicker system for the FAIR - synchrotron SIS 100

The different application of kicker magnets in synchrotrons requires an individual design of the magnet and the pulse generation. One has to fulfil the physical requirements as rise time, pulse length and deflection angle. The kicker system in the extraction section of SIS 100 have to comply with two demands; 1. Fast extraction of the beam to the experiments and 2. Destruction of the beam at any time onto an internal beam dump. To build a system which corresponds to these requirements as compact as possible, a bipolar kicker is planed to be used. It has the benefit that the decision of the field direction and therefore the deflection angle of the kicker system can be made shortly before the kick. This new technology and its challenges of pulse generation for a bipolar kicker are presented. The first measurement results from an experimental set-up demonstrate the realization of this new kicker version.
