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…
Nb3Sn multicell cavity coating system at JLAB
G. Eremeev, W. Clemens, K. Macha +5
SRF niobium cavities are the building blocks of modern accelerators for scientific applications. Lower surface resistance, higher fields, and high operating temperatures advance th…
Analysis of RF losses and material characterization of samples removed from a Nb3Sn-coated superconducting RF cavity
Uttar Pudasaini, Grigory V. Eremeev, Charles E. Reece +2
Nb3Sn (Tc ~ 18 K and Hsh ~ 400 mT) is a prospective material to replace Nb (Tc ~ 9 K and Hsh ~ 200 mT) in SRF accelerator cavities for significant cost reduction and performance en…
Initial Growth Of Tin On Niobium For Vapor Diffusion Coating Of Nb3sn
Uttar Pudasaini, Grigory Eremeev, Charles Reece +2
Nb3Sn has the potential to achieve superior performance in terms of quality factor, accelerating gradient and operating temperature (4.2 K vs 2 K) resulting in significant reductio…
Contribution to mid-field Q slope in Niobium SRF cavities from linear RF loss mechanism due to topographic surface structures
Chen Xu, Michael Kelley, Charles Reece
Topographic structure on Superconductivity Radio Frequency (SRF) surfaces can contribute additional cavity RF losses describable in terms of surface RF reflectivity and absorption…
Simulation of Non-linear SRF losses derived from characteristic topography of etched and electropolished niobium surfaces
Chen Xu, Charles E. Reece, Michael J. Kelley
A simplified numerical model has been developed to simulate non-linear superconducting radiofrequency (SRF) losses on Nb surfaces. This study focuses exclusively on excessive surfa…
