Description

The 1+/n+ method, early developed at the LPSC laboratory, is implemented at GANIL for the production of radioactive ion beams as well as for studying the production of intense stable metallic beams.

Regarding radioactive ion beam production, the SPIRAL1 charge breeder has been installed in the midst of the SPIRAL1 LEBT. Many modifications of the beam line and the ancillaries have been done to host the charge breeder. The first beam of $^{40}$Ar was extracted during May demonstrating a distribution peaked on the 9+ charge state with 16% in particle of ionization efficiency.

Concerning stable ion beam production, the GTS ion source, providing stable ion beam for the ARIBE facility, is under modification to include a charge breeding capability. The idea is to test the 1+/n+ method as an additional particle injection technique to produce high intensity metallic beam. Due to its high global efficiency (around 50%) and narrower charge state distribution, this technique has to be investigated to compete in numerous cases with the conventional methods: oven – sputtering – MIVOC.

This contribution will present preliminary results of the SPIRAL1 charge breeder set in its final location (SPIRAL1 facility) as well as the description of the 1+/n+ test bench for the production of intense metallic ion beam.
