Preface
This volume contains selected papers from the Seventh International Computational
Accelerator Physics Conference that took place 15-18 October, 2002 at Michigan State
University. Following a now well established tradition, the meeting succeeded the conference
in Darmstadt in 2000, and in turn will be followed by the conference in St. Petersburg, Russia
in 2004.
For the refereeing of the papers, we would like to acknowledge the help from a group of
sectional editors that assumed responsibility for certain groups of papers based on their
expertise. Their help was essential for the thorough refereeing and reviewing of the papers.
We would like to thank Bela Erdelyi, Alfredo Luccio, Stephan Russenschuck, Ursula van
Rienen, and Thomas Weiland for assuming responsibility of this important task.
The meeting would not have been possible without help from various sources. We are
grateful for financial support from the US Department of Energy, as well as from Tech-X and
Accel, who as representatives from the commercial world helped defray travel expenses of
graduate students who otherwise may not have been able to attend the meeting. Substantial
support was also provided by the MSU College of Natural Science and the Department of
Physics and Astronomy; specifically, we thank Lorie Neuman and Brenda Wenzlick for their
enthusiasm, professionalism, and seemingly never-ending patience.
