Niobium's intrinsic coherence length and penetration depth revisited using low-energy muon spin spectroscopy and secondary-ion mass spectrometry
Ryan M. L. McFadden, Jonathan W. Angle, Eric M. Lechner +7
We report direct, simultaneous measurements of the London penetration depth () and Bardeen-Cooper-Schrieffer (BCS) coherence length () in oxygen-doped niobium, with impur…
Analysis of Thermal Grooving Effects on Vortex Penetration in Vapor-Diffused Nb3Sn
Eric M. Lechner, Olga Trofimova, Jonathan W. Angle +2
While Nb3Sn theoretically offers better superconducting RF cavity performance (Q0 and Eacc) to Nb at any given temperature, peak RF magnetic fields consistently fall short of the 4…
RF surface resistance tuning of superconducting niobium via thermal diffusion of native oxide
Eric Lechner, Jonathan Angle, Fred Stevie +3
Recently, Nb superconducting radio frequency cavities vacuum heat treated between 300-400 C for a few hours have exhibited very high quality factors (~5x10^10 at 2.0 K). New second…
Advances in secondary ion mass spectroscopy
Jonathan Angle, Ari Palczewski, Charles E. Reece +2
Accurate SIMS measurement of nitrogen in niobium relies on the use of closely equivalent standards, made by ion implantation, to convert nitrogen signal intensity to nitrogen conte…
