Effect of substrate temperature on the growth of Nb3Sn film on Nb by multilayer sputtering
Md Nizam Sayeed, Uttar Pudasaini, Charles E. Reece +2
Nb3Sn films were fabricated by multilayer sequential sputtering on Nb at substrate temperatures ranging from room temperature to 250 °C. The multilayers were then annealed inside a…
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…
Properties of Nb3Sn films fabricated by magnetron sputtering from a single target
Md. Nizam Sayeed, Uttar Pudasaini, Charles E. Reece +2
Superconducting Nb3Sn films were fabricated on sapphire and fine grain Nb substrates by magnetron sputtering from a single stoichiometric Nb3Sn target. The structural, morphologica…
Effect of layer thickness on structural, morphological and superconducting properties of NbSn films fabricated by multilayer sequential sputtering
Md Nizam Sayeed, Uttar Pudasaini, Charles E Reece +2
Superconducting Nb3Sn films can be synthesized by controlling the atomic concentration of Sn. Multilayer sequential sputtering of Nb and Sn thin films followed by high temperature…
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…
