ECRISs at GANIL today and tomorrow
Abstract
GANIL (Grand accélérateur National d'Ions Lourds) uses ECRISs for producing stable and radioactive ions for more than 20 years. Two ECR4 type ion source (IS) deliver intense multi-charged stable ion beams of gaseous and metallic elements feeding cyclotrons for post acceleration to energies up to 100 A.MeV. A full permanent magnet ECRIS is also employed for producing multi-charged radioactive ion beams in the frame of SPIRAL 1 (Système de Production d'Ions Radioactifs Accélérés en Ligne, part 1). For atomic and material physic experiments, a high performance ECRIS labeled GTS developed at CENG/ Grenoble (France) is currently used to deliver high intensity, high charge state and low energy ion beams. To extend the range of radioactive ion beams available at GANIL, two ISOL (Isotope Separator On Line) projects are underway (SPIRAL1 upgrade and SPIRAL 2). In the frame of these projects, radiation hard singly-charged ECRIS, Q/A=1/3, 1/6 ECRISs, 2.45 GHz deuteron ECRIS and permanent magnet target ion source system (TISS) using an ECRIS are under development in parallel. A review of the main uses, current developments and performances obtained or expected with ECRISs at GANIL are presented. Locations of all the setups mentioned below are indicated in Figure 1.
