  Since 2001, the SPIRAL 1 facility has been one of the pioneering facilities
in ISOL techniques for reaccelerating radioactive ion beams: the fragmentation
of the heavy ion beams of GANIL on graphite targets and subsequent ionization
in the Nanogan ECR ion source has permitted to deliver beams of gaseous
elements (He, N, O, F, Ne, Ar, Kr) to numerous experiments. Thanks to the CIME
cyclotron, energies up to 20 AMeV could be obtained. In 2014, the facility was
stopped to undertake a major upgrade, with the aim to extend the production
capabilities of SPIRAL 1 to a number of new elements. This upgrade, which is
presently under commissioning, consists in the integration of an ECR booster in
the SPIRAL 1 beam line to charge breed the beam of different 1+ sources. A
FEBIAD source (the so-called VADIS from ISOLDE) was chosen to be the future
workhorse for producing many metallic ion beams. The charge breeder is an
upgraded version of the Phoenix booster which was previously tested in ISOLDE.
The performances of the aforementioned ingredients of the upgrade (targets, 1+
source and charge breeder) have been and are still being optimized in the frame
of different European projects (EMILIE, ENSAR and ENSAR2). The upgraded SPIRAL
1 facility will provide soon its first new beams for physics and further beam
development are undertaken to prepare for the next AGATA campaign. The results
obtained during the on-line commissioning period permit to evaluate intensities
for new beams from the upgraded facility.
