摘要:We report the finding of new surface treatments that permits one to manipulate the niobium resonator nitrogen content in the first few nanometers in a controlled way, and the resonator fundamental Mattis–Bardeen surface resistance and residual resistance accordingly. In part...

摘要:Nb3Sn has potential to become the material of choice for fabrication of SRF cavities. The higher critical temperature of Nb3Sn potentially allows for an increased operational temperature in SRF cavities, which could enable a simplification of the cryogenic s...

摘要:Neutron Compton scattering and neutron diffraction have been applied to investigate the influence of nitrogen doping of niobium on the performance of superconducting radio-frequency niobium cavities. To this end, a comparative study of the neutronic response of two samples has be...

摘要:We report a surface treatment that systematically improves the quality factor of niobium radio frequency cavities beyond the expected limit for niobium. A combination of annealing in a partial pressure of nitrogen or argon gas and subsequent electropolishing of the niobium cavity...
