Abstract : The GANIL facility is drastically extending its possibilities with new projects, so
increasing its capabilities in nuclear physics. The most significant one is the Spiral2
installation based on a linear accelerator, then to be associated with the S3, NFS
and DESIR new experimental rooms. Beside of the legacy home made control
system handling the original installation, Epics was chosen as the basic framework
for these projects. First, some control system components were used during preliminary
beam tests. In parallel, the whole architecture was designed while the
organization for future operation started to be considered; also, more structured
and sophisticated tools were developed and the first high level applications for the
whole machine tuning started to be tested, jointly with the current onsite beam
commissioning. Progression of the control system development is presented, from
the first beam tests up to the whole Spiral2 commissioning. Then, according to
the new projects to cope with, some highlights are given concerning the related
organization as well as specific items and developments to be considered, taking
benefit from the Spiral2 control system feedback experience.
