Upgrade of the GTS Electron Cyclotron Resonance Ion Source at GANIL
Résumé
The GTS (Grenoble Test Source) electron cyclotron resonance ion source, operated at 14.5
GHz, provides multiply charged heavy ion beams for the ARIBE (Accélérateurs pour les
Recherches Interdisciplinaires avec les Ions de Basse Energie) facility at GANIL (Grand Accélérateur
National d’Ions Lourds). In order to increase the beam currents and charge states
available for experiments and to have a test bench with good performance for the R&D of
new beams for GANIL users, the ion source has undergone a number of upgrades. These
include the refurbishment of the extraction system and the addition of a new central coil.
The injection side of the source will also be replaced in the future. A simulation approach
has been used in parallel to the upgrades to identify potential performance limitations in the
beam extraction and low energy beam transport sections. In addition, metal ion beam production
with the MIVOC method has been tested for the first time with the GTS to expand
the beam catalogue available for the ARIBE experiments. The performance of the upgraded
GTS will be presented along with the results from the simulation studies and the MIVOC
tests.
