Title: The CERN development of Superconducting Sputtered Nb/Cu QWR for the HIE-ISOLDE Project
Author: Giulia Lanza
Institution: CERN – Geneva
Abstract: For the foreseen upgrade of the ISOLDE complex a new superconducting LINAC based on sputtered Nb/Cu Quarter Wave Resonators (QWRs) of two different beta families is planned to be installed in the next three to five years. The niobium coating process has been developed at CERN and the newly constructed biased magnetron system has shown that the target performance in terms of RRR and Tc can been achieved on samples. A first prototype resonator, of the higher beta family, has been coated and characterized in RF.
In this talk the latest developments on the sputtering technique and the first cold RF measurements will be reported.
