Development of High-Q SRF Structures by Nitrogen Doping for Superconducting Electron Linacs
- Fermi National Accelerator Lab. (FNAL), Batavia, IL (United States)
One of the most exciting recent developments in superconducting RF technology has been the discovery of a nitrogen-doping process which can reliably increase the superconducting quality factor of niobium resonators well above 1010 at high frequency (>1 GHz). This process is now well demonstrated in particular for TESLA-style 9-cell cavities at 1.3 GHz. Nitrogen doping can significantly increase efficiency of the cavities as well as the cryogenic efficiency accelerators, and allowing significant capital cost reductions. This project will expand the application of nitrogen doping into the low-frequency regime and investigate and quantify effects on the quality factor in low frequency superconducting structures from the nitrogen doping process.
