Acknowledgements

I would like to thank Michael Boege and Lenny Rivkin for their generous effort to teach me so much about accelerator physics and their kind supervision. Even when they were under great workload they always took time to give me additional advice. I am greatful to Jan Chrin for his explanations about the Corba environment and the software used in the beam dynamics group as well as to Andreas Luedecke for his explications concerning technical aspects of the accelerator. Finally, I thank the whole team at SLS for these very interesting weeks, their valuable information and their kind and encouraging climate. I have learned much and experienced many great hours here at SLS.
