N-doped surfaces of superconducting niobium cavities as a disordered composite-addendum

Wolfgang Weingarten

Experimental data on N-doped superconducting (sc) cavities are further analyzed which contribute to confirm a recently proposed model explaining the increase of the Q-value versus…

Field-dependent surface resistance for superconducting niobium accelerating cavities -- condensed overview of weak superconducting defect model

Wolfgang Weingarten

Small (compared to coherence length) weak superconducting defects when located at the surface, combined with the proximity and percolation effects, are claimed responsible for vari…

Comment on Field-dependent surface resistance for superconducting niobium accelerating cavities

Wolfgang Weingarten

First, this is a response to a criticism I have received about the paper which is mentioned in the title. Second, the aim is to show the important role of small (compared to cohere…

Fluxon-induced losses in niobium thin-film cavities revisited

Wolfgang Weingarten

Long standing data from niobium thin film accelerating cavities will be revisited and analysed by a modified London model of RF superconductivity. Firstly, the applicability of thi…

N-doped surfaces of superconducting niobium cavities as a disordered composite

Wolfgang Weingarten

The Q-factor of superconducting accelerating cavities can be substantially improved by a special heat treatment under N2 atmosphere (N-doping). Recent experiments at Fermi National…

On superconducting niobium accelerating cavities fired under N2-gas exposure

Ralf Eichhorn, Daniel Gonnella, Georg Hoffstaetter +2

The dependence of the Q-value on the RF field (Q-slope) is actively studied in various accelerator laboratories. Although remedies against this dependence have been found, the phys…
