This book helps to dispel the notion that collective phenomena, which have become increasingly important in modern storage rings, are an obscure and inaccessible topic. Despite an emphasis on synchrotron light sources, the basic concepts presented here are valid for other facilities as well. Graduate students, scientists and engineers working in an accelerator environment will find this to be a systematic exposition of the principles behind collective instabilities and lifetime-limiting effects. Experimental methods to identify and characterize collective effects are also surveyed. Among other measures to improve the performance of a projected or existing facility, a detailed account of feedback control of instabilities is given.

Résumé
This book is intended to dispel the notion that collective phenomena are an obscure and inaccessible topic. Having become increasingly important in modern storage rings, collective e?ects deserve to become part of the general education in accelerator physics. ItriedtowritethebookIwaslookingforwhenIstartedtostudycollective instabilities: an introduction that can be read from cover to cover with m- erate e?ort and familiarizes the reader with the basic concepts. Self-contained appendices contain what I considered worth discussing but might impair the readability of the main text, such as a reminder of basic relations and some background information on selected topics. Finally, an extensive list of r- erences was compiled (with some emphasis on accessibility of the source) in order to facilitate the search for more detailed information. A previous version of the present text was submitted in German language as Habilitationsschrift a postdoctoral thesis, which is a peculiarity of the German academic system to the Humboldt University of Berlin. It grew from my occupation with collective phenomena over ten years at the thi- generation synchrotron light source BESSY II. This has some consequences regarding the character of this text: • Thereisaclearemphasisonsynchrotronlightsourcesandelectronstorage rings. However, many concepts (wake ?eld, impedance, beam spectrum, beam lifetime, etc.) are quite general. • The selection of material re?ects my personal experience and some readers may want to skip over details that I considered important, while others may ?nd that their favorite topic was not covered in su?cient detail.
