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.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
