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.

The 7th International Cyclotron Conference, In addition to 25 invited papers, a total of held in ZUrich from 19-22 August, 1975, was atten 103 papers were submitted for presentation at the ded by 231 registered . participants from 21 different conference. In order to avoid parallel sessions, countries. Visitors came from all 5 continents, only 30 papers were selected for oral presentation. showing the truly international character of the The rest of the papers were displayed, with great so-called cyclotron family. After a slight slump success, in two poster sessions, with the authors around 1970 in science funding in general, it is explaining in detail to interested participants encouraging to see that cyclotrons emerge again their reports. The high-light of the banquet was the with a promising future, rich in applications. For after dinner speech by M. S. Livingston on the history an informal summary of the topics and highlights of of the cyclotron. The hit of the ladies program was this conference, the reader is referred to the back the visit to a local chocolate factory. The rumour inside cover of these proceedings. There Henry goes that some conference participants too preferred Blosser, from Michigan State University, a very this visit to the session talks! active pioneer in the cyclotron field, put down his impressions in a matter of ten minutes after some The list of old-timers who participated in all small pressure from the editor.

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.

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.

Cyclotrons '98 is the 15th of a series of international conferences which was initiated in 1959. The proceedings provide a review of progress in the field of cyclotron design and technology as well as in the development of applications of this type of particle accelerator. Cyclotrons are used in basic and applied research, radiotherapy and nuclear medicine. Both theoretical and experimental contributions are included. In addition, a complete list of existing cyclotrons with their characteristics is given.
