Title: Performance-defining properties of Nb₃Sn coating in SRF cavities

Abstract

Nb₃Sn has potential to become the material of choice for fabrication of SRF cavities. The higher critical temperature of Nb₃Sn potentially allows for an increased operational temperature in SRF cavities, which could enable a simplification of the cryogenic system, leading to significant cost reduction. We present extended characterization of a Nb₃Sn coated Nb cavity prepared at Cornell University. Using a combination of thermometry during cavity RF measurements, and structural and analytical characterization of the cavity cutouts, we discovered Nb₃Sn coating flaws in regions that exhibit significant heating during the RF testing. Results of extended comparison of cavity cutouts with different dissipation profiles not only indicate the cause of significant Q degradation but also establish figures of merit for material qualities in relation to the quality of SRF performance.

Growth and Properties of Vapor Diffused Nb3Sn Coating for Superconducting Radiofrequency Accelerator Cavity Applications

Thesis/Dissertation Pudasaini, Uttar

The desire to reduce construction and operating costs of future SRF accelerators motivates the search for higher-performing alternative materials. Nb3Sn (Tc ~ 18.3 K and Hsh ~ 425 mT) is the front runner. The tin vapor diffusion process is currently the technique of choice to produce promising Nb3Sn-coated cavities. Understanding Nb3Sn nucleation and growth in this process is essential to progress. Samples representing different stages of Nb3Sn formation have been produced and studied to elucidate the effects of nucleation, growth, process conditions, and impurities. Nb3Sn films with thickness from a few hundred nm up to ~15 µm were grown andmore »« less

Grain-boundary structure and segregation in Nb₃Sn coatings on Nb for high-performance superconducting radiofrequency cavity applications

Journal Article Lee, Jaeyel ; Mao, Zugang ; He, Kai ; ... - Acta Materialia

Here, we report on atomic-scale analyses of grain boundary (GB) structures and segregation in Nb₃Sn coatings on Nb, prepared by the vapor-diffusion process, for superconducting radiofrequency (SRF) cavity applications, utilizing atom-probe tomography, high-resolution scanning transmission electron-microscopy and first-principles calculations. We demonstrate that the chemical composition of Nb₃Sn GBs is correlated strongly with the diffusion of Sn and Nb at GBs during the coating process. In a sample coated with a relatively large Sn flux, we observe an interfacial width of Sn segregation at a GB of ~3 nm, with a maximum concentration of ~35 at.%. After post-annealing at 1100 °Cmore »« less

Analysis of RF losses and material characterization of samples removed from a Nb₃Sn-coated superconducting RF cavity

Journal Article Pudasaini, Uttar ; Eremeev, Grigory ; Reece, Charles E. ; ... - Superconductor Science and Technology

Nb₃Sn (T_c≈18 K and H_sh≈400 mT) is a prospective material to replace Nb (T_c≈9 K and H_sh≈200 mT) in SRF accelerator cavities for significant cost reduction and performance enhancement. Because of its material properties, Nb3Sn is best employed as a thin film (coating) inside an already built RF cavity structure. A particular test cavity noted as C3C4 was a 1.5 GHz single-cell Nb cavity, coated with Nb3Sn using Sn vapor diffusion process at Jefferson Lab. Cold measurements of the coated cavity indicated the superconducting transition temperature of about 18 K. Subsequent RF measurements indicated field-dependent surface resistance both at 4.3more »« less

Novel SRF Cavity Fabrication

Technical Report Rey, Christopher ; Andrews, Ben

Energy to Power Solutions (e2P) in collaboration with the Thomas Jefferson National Accelerator Facility (JLAB), ExOne Corporation, and the Hackett-Brass Foundry, proposed a revolutionary approach to Nb₃Sn SRF cavity fabrication using synergistic technologies consisting of high quality Nb thin films deposited on low cost bulk “casted” bronze (Cu-Sn) substrates. e2P’s proprietary Nb₃Sn SRF cavity fabrication process (see US 62/087557 and 62/631,067) can be thought of as the “inverse” process of existing state-of-the-art technology (i.e. Sn diffused bulk Nb) [vi], where the Sn content in our process is provided by an “infinite” reservoir from the underlying bulk bronze (Cu-Sn) scaffold andmore »« less
Biased deposition of Nb-ON-Cu for SRF accelerators, Final Report

Technical Report Velas, Katherine ; Krishnan, Mahadevan ; Chapman, Steve ; ...

The Phase I project objectives were: Task 1: Design, assemble, and commission a new coating facility that uses the RF cavity as the vacuum chamber Task 3: Coat and RF test biased Cu cavity Task 4: Evaluate test results and prepare Ph-II bid. As for project accomplishments, AASC has completed all of the tasks of Ph-I. However, for Task 2, we found a limit to the bias voltage on a substrate placed at the radius of the beam pipe. A bias voltage higher than -50 V can induce arcing from the substrate to the grounded anode. Arc spots form onmore »« less
