Design and Fabrication of a Quadrupole Resonator for Sample R amp;D

Being able to obtain BCS surface resistance and material properties from the same surface is necessary to gain a fundamental understanding of the evolution of SRF surfaces. A test resonator which will allow to obtain BCS properties from samples is currently under development at Universität Hamburg UHH and DESY and is based on the Quadrupole Resonators developed and operated at CERN [1] and HZB [2]. The current status of the necessary infrastructure, the procurement process and design considerations are shown. In addition, an outline of the planned R amp;D project with the Quadrupole Resonator will be presented and first RF measurements and surface analysis results of samples will be show
