Grenoble Test Source (GTS) is a room temperature electron cyclotron resonance ion source whose purpose is to deepen the knowledge of this type of device. GTS was designed according to magnetic scaling laws determined with the SERSE source [Hitz et al., Rev. Sci. Instrum. 73, 509 (2002); Gammino et al., ibid. 72, 4090 (2001)] while keeping enough flexibility in terms of magnetic confinement and rf heating to determine best conditions for the production of intense beams of any charge state. First results were presented 1 year ago [Hitz et al., 8th European Particle Accelerator Conference, 2002; 15th International Workshop on ECR Ion Sources, 2002]. Since then, some improvements have been performed mostly in the magnetic confinement, beam extraction and analysis. Updated ion beam intensities are presented: e.g., 0.5 mA of Ar11+ at 18 GHz, 20 μA of Ar16+ and 1.8 μA of Ar17+ when GTS is operated at 14.5 GHz. On the other hand, charge coupled device imagers have been installed to diagnose and monitor the ion be...

For the needs of future heavy ions accelerators, electron cyclotron resonance ion sources (ECRIS) should be able to deliver intense beams of multiply charged ions. The 1 emA level intensity has been reached by ECRIS for medium charge states (e.g. O6+, Ar8+). However, thanks to a better optimization of the ionic lifetimes inside the ion source, high charge states intensities are also been improved. After a presentation of some scaling laws governing the ECRIS behavior, different ion sources will be shown: new compact all permanent magnet source shown, upgrade of the CAPRICE type source and a fully superconducting source.

The Quadrumafios electron cyclotron resonance ion source (ECRIS) has been especially designed to permit physical studies of the plasma; this paper describes the source itself (which has been operated at 10 GHz in a first step), its preliminary performances, and the different diagnostics involved, which mainly concern the electron population [electron cyclotron emission (ECE), x rays, diamagnetism, microwave interferometer, and electron analyzer]. The results are presented and discussed: There is of course a close relationship between the parameters of the plasma and the performances of the source; this point will be discussed in the article.

A new high voltage platform has been installed at the ORNL Multicharged Ion Research Facility (MIRF) to extend the energy range of multicharged ions available for experiments studying their collisional interactions with electrons, atoms, molecules, and solid surfaces. For the production of the multiply charged ions, a new all‐permanent magnet ECRIS has been designed and fabricated at CEA/Grenoble. After a brief overview of the basic features of the new platform, and associated beam transporta detailed description of the new ion source design and performance is provided, together with some typical Ar, Xe, and O beam intensities obtained during source commissioning prior to shipment to ORNL.
