Reihe: Particle Acceleration and Detection

This book helps dispel the notion that collective phenomena, which have become increasingly important in modern storage rings, are an obscure and inaccessible topic. The book serves as a valuable guide on how to improve synchrotrons and other storage rings. Despite an emphasis on synchrotron light sources, the basic concepts presented here are valid for other facilities as well.

1987: graduation in nuclear physics at University Heidelberg
1989-1993: working in elementary particle physics at DESY/Hamburg - participation in the ARGUS experiment
1993-today:  working in accelerator physics, participation in design, construction and operation of the BESSY II synchrotron radiation source in Berlin,
2003: Habilitation at the Humboldt-University Berlin
