Abstract

8 high-β Nb/Cu superconductive QWR cavities should be coated for the ALPI upgrade in the framework of the SPES facility. The QWR cavities should require specific superconductive performance to be assembled in the ALPI linac. RF test cold measurements are used for evaluation of the coated Nb/Cu quality. Meanwhile, verification of the QWRs superconductive properties, which are currently used in the ALPI on-line activity, is also made with RF measurements. Methodology and results of the sputtered QWRs RF measurements will be described in this paper. In particular, cold test results of the ALPI cryostat 7 medium-β QWR cavities will be mentioned.
