SPIRAL2 cryomodules: status and first tests results
Résumé
The SPIRAL2 superconducting linac will be composed
of 19 cryomodules of two different types: 12 low-beta
cryomodules (so called A) housing a single Quarter-Wave
Resonator (QWR) each (beta 0.07, 88 MHz) followed by
7 high-beta cryomodules (so called B), housing a couple
of QWRs each (beta 0.12, 88 MHz).
A prototype of each cryomodule type (called qualifying
cryomodule) has been constructed by the industry and
successfully tested at 4.5 K and high power (P max=10 kW)
in 2009. The results of these qualification tests will be
presented as well as the status on cryostats, cavities and
RF couplers production.
