Devanz Keywords: Linear accelerator; Superconducting RF cavities; Radio frequency; Ion beam Abstract: The SPIRAL 2 project to be built in GANIL is a high intensity ion linear accelerator for radioactive beam production. Most of the acceleration is provided by twenty four 88MHz quarter wave resonators breaking into two beta families. The first ([beta] =0.07) was developed at CEA-Saclay, while the second ([beta] =0.12) was studied at IPN-Orsay. Each team has carried out the integration study of the QWRs in their respective cryomodule taking into account tight longitudinal space requirements. Prototypes of each cavity type have been built, prepared and tested in vertical cryostats. We present the RF and mechanical design of the resonators, cryostats, the preparation and test equipment specifically developed for QWRs, as well as the RF test results.
