The GANIL (Grand Accélérateur National d’Ions Lourds) in Caen produces up to 20 % of the beam times dedicated to industrial applications, such as the irradiation of electronic components. The SAGA (Space Application at GAnil) project aims to increase beam times for these applications in the future in order to meet demand from French and European industries. In this context, one of the challenges is to be able to switch rapidly from one beam to another in order to optimize the beam time available to industry. To meet these requirements, CIME’s cyclotron could be an interesting device: it is capable of accelerating beams up to 20 MeV/A for light elements, and it can be used as a mass separator to select the desired beam. In order to supply stable ion beams to the CIME cyclotron, the charge breeder installed on the SPIRAL1 facility has been tested and adapted to provide a stable cocktail-type beam with a very close A/Q. Details of the project and initial results will be described.

This paper presents an innovative solution to address the issue of asymmetric dipole fields in the injection region of the TRIUMF electron cyclotron resonance ion source charge state booster. The asymmetric fields arise from a wide gap in the booster’s injection soft iron plug, which allows the connection of the RF waveguide to the plasma chamber. Simulations have revealed that singly charged ions, injected for charge breeding, experience deflection and get lost due to the asymmetric magnetic fields instead of being effectively captured by the plasma, thereby diminishing the efficiency of the charge state booster. To rectify this problem, a novel iron plug with an enlarged inner diameter, which allows the RF waveguide to connect to the plasma chamber with no gap was designed. Furthermore, this new design necessitates alterations to the injection electrodes and plasma chamber of the booster. Additionally, the waveguide and gas-inlet windows were repositioned to ensure better RF coupling into the plasma cavity. By eliminating the gap and implementing these design changes, it is anticipated that the TRIUMF charge state booster will operate at the same overall efficiency as other PHOENIX boosters.
