Performances of SPIRAL2 low and high beta cryomodules
Résumé
All SPIRAL2 cryomodules (twelve with one quarter
wave resonator (QWR) at β=0.07 and seven with two
QWRs at β=0.12) have been produced and qualified, and
are now in installation phase on the LINAC at GANIL.
After a general introduction on the LINAC, we will first
remember and compare the different design choices taken
for the two families of cryomodules. We will then present
a summary of the techniques used for the preparation and
integration of the cavities in the cryomodules, and
compare the achieved performances with design
parameters. At last, we describe the status of the LINAC
installation as of end of August 2015.
