NB film engineering with energetic condensation for tailored RF behavior
- Thomas Jefferson National Accelerator Facility (TJNAF), Newport News, VA (United States)
The different processes involved in energetic condensation are exploited in ECR (electron cyclotron resonance) generated plasma deposition and HiPIMS to tailor SRF film growth in sequential steps. The resulting Nb/Cu films display high quality material and show promise of high RF performance. The residual and flux induced surface resistance contributing factors are investigated with RF measurements at different temperatures and frequencies coupled with film material and superconducting properties characterization with various microscopy and magnetometry techniques. Results show that the manipulation of the interface, film nucleation and growth allows to tailor fundamental properties of the material to minimize surface resistance and field dependent losses.
