Abstract

A compact ECR source, BECRIS (Berlin Electron Cyclotron Resonance Ion Source), has been developed. Only permanent magnets were used to obtain the magnetic field configuration for a radio frequency of 5 GHz. The source operates at external pressures up to 6 atm. It has been installed on the high voltage terminal of a 6 MV CN Van de Graaff accelerator which is used as a stand-alone machine and as an injector of the VICKSI cyclotron at HMI. With a total power consumption of less than 1 kW both, high currents of lowly charged and reasonable currents of highly charged ions, have been produced. This source improves the intensity and energy variability of beams with single-ended machines. Test results and first operating experience with the source on the high-voltage terminal on the CN are presented.

Development of intense high-energy noble gas ion beams from in-terminal ion injector of tandem accelerator using an ECR ion source

On the other hand, modern electron cyclotron resonance ion sources (ECRISs) have been able to produce intense beams of highly charged ions over a wide range of charge states [5], and they are very suitable for noble gas ionizations. With such an ECRIS installed on a positively charged high voltage terminal of tandem accelerator, the intensity and energy range may be increased for noble gas ion beams compared to those of nearly heavy non-noble gas ion beams normally obtained from the tandem accelerator [6,7]. In the present work, a compact 10 GHz ECRIS was chosen for the in-terminal ECRIS (T-ECRIS) injector of the vertically folded type 20UR PelletronTM tandem accelerator at Japan Atomic Energy Agency (JAEA)-Tokai is illustrated in Fig. 1 [8–11].
An ECRIS-based heavy ion injector was constructed in the high-voltage terminal of JAEA-Tokai Tandem Accelerator to develop new beam species of highly charged noble gas ions. This work was associated with a lot of development to operate the ion source on the 20UR Pelletron high voltage terminal in high pressure SF₆ gas environment. Highly charged ions of N, O, Ne, Ar, Kr and Xe have been accelerated satisfactorily. Operating data integrated during many years long beam delivery service are summarized.
Modern applications of high energy ion beams: From single-event burnout to human eye cancer treatment
1996, Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and Atoms
Energetic ion beams, originally the domain of nuclear physics, become increasingly important tools in many other fields of research and development. The choice of ion species and ion energy allows an enormously wide variation of the penetration depth and of the amount of the electronic stopping power. These features are utilized to modify or damage materials and living tissues in a specific way. Materials modification with energetic ion beams is one of the central aims of research and development at the ion beam laboratory, ISL-Berlin, a center for ion-beam applications at the Hahn-Meitner-Institut Berlin. In particular, energetic protons will be used for eye cancer treatment. Selected topics such as the “single-event burnout” of high power diodes and the eye cancer therapy setup will be presented in detail.
