First HIE-ISOLDE cryo-module assembly at CERN

The first phase of the HIE-ISOLDE project aims to increase the energy of the existing REX ISOLDE facilities from 3MeV/m to 5MeV/m. It involves the assembly of two superconducting cryo-modules based on quarter wave resonators made by niobium sputtered on copper. The first cryo-module was installed in the linac in May 2015 followed by the commissioning. The first beam is expected for September 2015. In parallel the second cryo-module assembly started. In this paper, we present the different aspects of these two cryo-modules including the assembly facilities and procedures, the quality assurance and the RF parameters (cavity performances, cavity tuning and coupling)
