The international conference held in Berlin is the 12th in the series of meetings to provide the exchange of ideas and information by cyclotron builders and users throughout the world. The international character is confirmed by the number of countries represented, the general interest by the numbers of contributions and participants. The Berlin conference which was organized by the Hahn-Meitner-Institut Berlin, had about 220 participants from 22 countries with about 165 contributions, thereof 16 invited.

These conference proceedings will be of interest to all accelerator scientists and engineers, as well as those concerned with the application of cyclotrons in various fields. The conference covers the latest developments in the science, technology and use of cyclotrons, and includes more than 25 invited talks by specialists in their respective fields. Contributions include papers on newly operating cyclotrons and facilities under construction, compact cyclotrons, cooler rings and post-accelerators, ion sources, beam dynamics, beam diagnostics, cyclotron components, systems and technologies, as well as medical applications — including radiotherapy and radioisotope production — non-medical applications, radioactive beam facilities and new projects and proposals.

This volume describes the latest developments in the design, construction and operation of cyclotrons, from compact machines producing intense beams for isotope production, cancer therapy and industrial use, to the larger versions giving higher energy beams of ions of various elements for nuclear and particle physics. Important topics include ECR ion sources, superconducting magnets and radiofrequency cavities, beam dynamics and diagnostics, beam cooling rings, control systems and various medical and industrial applications.
