Charge breeder for the SPIRAL1 upgrade: preliminary results
Résumé
In the framework of the SPIRAL1 upgrade under progress at the GANIL lab, the charge breeder
based on a LPSC Phoenix ECRIS, first tested at ISOLDE has been modified to benefit of the
last enhancements of this device from the 1+/n+ community. The modifications mainly concern
the 1+ optics, vacuum techniques, and the RF—buffer gas injection into the charge breeder. Prior
to its installation in the midst of the low energy beam line of the SPIRAL1 facility, it has been
decided to qualify its performances and several operation modes at the test bench of LPSC lab. This
contribution shall present preliminary results of experiments conducted at LPSC concerning the 1+
to n+ conversion efficiencies for noble gases as well as for alkali elements and the corresponding
transformation times.
