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 as to benefit of the last enhancements of this device from the 1+ / n+ community**. Prior to its installation in the middle of the low energy beam line of the SPIRAL1 facility, it has been tested at the 1+/n+ LPSC test bench to validate its operation performances. Charge breeding efficiencies as well as charge breeding times have been measured for noble gases and alkali elements. The experimental results demonstrated that the modifications done were on the right track leading the SPIRAL1 charge breeder to the top worldwide in terms of performances. The experimental outcomes have proved the strong interrelationship between the charge breeding efficiency and the charge breeding times which are still under active discussion.
