A TWIN INTERNAL ION SOURCE FOR PARTICLE BEAM PRODUCTION WITH A CYCLOTRON

摘要

The present invention, which comprises two internal ion source (1, 2) for the generation of the same particles relates to a cyclotron. A second ion source to increase the reliability and uptime strongly cyclotron, an interruption for maintenance can be used as a spare ion source to reduce. Advantageously, the cyclotron is further characterized by an optimized close-up members of a different geometry in the central region of the cyclotron. Cyclotron of the present invention is a modification and optimization of the first internal ion source and the second shape of the internal ion source further characterized in order to avoid particle losses during the first rotation acceleration. In order to improve the acceleration of the cyclotron is between gap (5), and possible de-electrode assembly (4) of the counter may be further characterized by a shape adaptation and optimization of the di-electrode assembly. ;
