Trapped Charged Particles and Fundamental Interactions: I. Invited papers from the conference, Wildbad Kreuth, Germany, 25-30 August 2002 This international conference was the third in the series on Trapped Charged Particles and Fundamental Interactions (TCPFI). This meeting, following on from those held in Lysekil (Sweden) in 1994 and Monterey, CA (USA) in 1998, was organized in Wildbad Kreuth (Germany) within the framework of the WE-Heraeus seminar series. The conference highlighted the wide application and multi-disciplinary nature of the field of trapped charged particles with talks and posters covering topics from elementary particle and nuclear physics, one-component plasma and beam physics, through to precision metrology and quantum information processing. To illustrate the wide application and highlight the new results and technical challenges of the trapped charged particle physics presented at this conference, Journal of Physics B: Atomic, Molecular and Optical Physics (JPB) is publishing two special sections containing articles based on talks and presentations from the TCPFI conference. These articles were carefully selected by the conference organizers and reviewed by JPB. The first special section (starting on p 499 of this issue) contains papers based on the invited talks. The second section, containing articles based on selected oral and poster presentations, will appear in issue 5 (publication date 14 March 2003) of JPB. Finally, the organizers would like to thank the international advisory committee (see below) for their support, and the delegates for making it a very successful and interesting conference. The beautiful conference site at Wildbad Kreuth (shown in the figure below) and the genuine Bavarian entertainment generated the atmosphere for a successful exchange of new ideas between the renowned experts in the fields and a large number of younger scientists.
