Design optimization, commissioning, and uncertainty analysis of the quadrupole resonator system at Jefferson Lab for SRF material characterization
Mingqi Ge, Sarra Bira, Kristof Brunner +14
A quadrupole resonator (QPR) provides a sample-based platform for characterizing materials for superconducting radio-frequency (SRF) applications under controlled field, frequency,…
Nb3Sn coating of SRF cavity by co-sputtering from a composite target
Md Sharifuzzaman Shakel, Grigory V. Eremeev, Anne-Marie Valente-Feliciano +2
We deposited Nb3Sn film on the inner surface of a 2.6 GHz Nb superconducting radiofrequency (SRF) cavity by co-sputtering using a composite of Nb and Sn tube targets in a DC cylind…
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…
Preservation of the High Quality Factor and Accelerating Gradient of Nb3Sn-coated Cavity During Pair Assembly
G. Eremeev, U. Pudasaini, S. Cheban +6
Two CEBAF 5-cell accelerator cavities have been coated with Nb3Sn film using the vapor diffusion technique. One cavity was coated in the Jefferson Lab Nb3Sn cavity coating system,…
First Results from Nb3Sn Coatings of 2.6 GHz Nb SRF Cavities Using DC Cylindrical Magnetron Sputtering System
M. S. Shakel, H. E. Elsayed-Ali, G. Eremeev +2
A DC cylindrical magnetron sputtering system has been commissioned and operated to deposit Nb3Sn onto 2.6 GHz Nb SRF cavities. After optimizing the deposition conditions in a mock-…
First Results From Nanoindentation of Vapor Diffused Nb3Sn Films on Nb
U. Pudasaini, G. V. Eremeev, S. Cheban
The mechanical vulnerability of the Nb3Sn-coated cavities is identified as one of the significant technical hurdles toward deploying them in practical accelerator applications in t…
