 Internal Note Report number HIE-ISOLDE-PROJECT-Note-0020 ; CERN-HIE-ISOLDE-PROJECT-Note-0020 Title Steady-state thermal studies on the HIE-ISOLDE high-$\beta$ superconducting cavities Author(s) Alberty, L Corporate author(s) CERN. Geneva. HIE-ISOLDE Department Imprint 28 May 2013. - 26 p. Subject category Accelerators and Storage Rings Accelerator/Facility, Experiment CERN ISOLDE Project CERN HIE-ISOLDE Keywords HIE-ISOLDE ; Superconducting Cavity ; Quarter Wave Resonator Abstract The activity of the High Intensity and Energy ISOLDE (HIE-ISOLDE) project aims to construct a superconducting linac based on 101.28 MHz niobium sputtered Quarter Wave Resonators (QWRs). For this, several prototypes of superconducting cavities are currently being developed at CERN using OFE copper as substrate material for Niobium film coating. Two main concepts are currently under development: one consists of rolled, machined, deepdrawed and welded parts; the other is based on machined parts which are put together using electron beam welding. This study presents the results of simulations carried out in order to assess the thermal performance of different designs. The interest for such analysis was raised up before launching the manufacture of the first industrial series, since both rolled and bulk approaches seemed possible.
