Abstract
The SPIRAL2 linac is now successfully commissioned;
H+, 4He2+, D+ and 18O6+ have been
accelerated up to nominal parameters and 18O7+ and
40Ar14+ beams have been also accelerated up to
7 MeV/A. The main steps with 5 mA H+, D+ beams
and with 0.6 mA 18O6+ are described. The general results
of the commissioning of the RF, cryogenic and diagnostics systems,
as well as the preliminary results of the first experiments on NFS
are presented. In addition of an improvement of the matching to the
linac, the tuning procedures of the 3 Medium Energy Beam Transport
(MEBT) rebunchers and 26 linac SC cavities were progressively
improved to reach the nominal parameters in operation, starting from
the classical “signature matching method”. The different cavity
tuning methods developed to take into account our particular
situation (very low energy and large phase extension) are
described. The tools developed for an efficient linac tuning in
operation, e.g. beam energy and intensity changes are also
discussed.
