High intensity metallic ion beams from an ECR ion source at GANIL

Superconducting Ecr Ion Sources: High Intensity Beams Extraction and Transport

In the last decade a relevant step forward in the design of Electron Cyclotron Resonance Ion Sources (ECRIS) have been obtained and some high performance sources have been built, at the operating frequency of 14,18 and 28 GHz. In particular, the total extracted current exceeds 5 mA in cw mode for some of them, at voltage between 10 and 40 kV. A potential drawback of such intense beams consists ...

Ion source developments for stable and radioactive ion beams at Ganil

Since now many years, the Ganil ion source team deals with high charge state and radioactive ion beam production. Concerning radioactive ion production, the recent results obtained, in collaboration with the ISN Grenoble group, with the 1+/n+ method drove us to develop a new concept of ecr ion source for monocharged ion production. The results of the first tests of this source are given. This n...

Direct Injection of Intense Heavy Ion Beams from a High Field Ecr Ion Source into an Rfq

Beam intensities achievable from high performance ECR sources for highly charged ions are limited by the high space charge. For high performance ECR sources, the stray magnetic field of the source can provide focusing against the space charge blow-up of the beam when used with the Direct Plasma Injection Scheme (DPIS) developed for laser ion sources. A combined extraction/matching system has be...

An Ecr Hydrogen Negative Ion Source at Cea/saclay: Preliminary Results. I -introduction Ii -silhi, High Intensity Proton Source

The development of a high intensity negative ion source is part of a considerably larger activity presently undergoing at CEA Saclay in the field of high intensity linear accelerators. Preliminary studies toward the construction of a 2.45 GHz ECR H-ion source have been performed for few months. This new test bench takes advantage of our experience on the French high intensity proton source SILH...
