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…
Secondary ion mass spectrometry for SRF cavity materials
J. Tuggle, U. Pudasaini, A. S. Palczewski +3
Historically, many advances in superconducting radio frequency (SRF) cavities destined for use in advanced particle accelerators have come empirically, through the iterative proced…
Effect of high temperature heat treatments on the quality factor of a large-grain superconducting radio-frequency niobium cavity
P. Dhakal, G. Ciovati, G. R. Myneni +10
Large-grain Nb has become a viable alternative to fine-grain Nb for the fabrication of superconducting radio-frequency cavities. In this contribution we report the results from a h…
