Advanced surface treatments for medium-velocity superconducting RF cavities for high accelerating gradient continuous-wave operation
K. McGee, S. Kim, K. Elliott +13
Nitrogen-doping and furnace-baking are advanced high-Q0 recipes developed for 1.3 GHz TESLA-type cavities. These treatments will significantly benefit the high-Q0 linear accelerato…
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,…
Commissioning of Dedicated Furnace for Nb3Sn Coatings of 2.6 GHz Single Cell Cavities
P. A. Kulyavtsev, G. Eremeev, S. Posen +2
We present the results of commissioning a dedicated furnace for Nb3Sn coatings of 2.6 GHz single cell cavities. Nb3Sn is a desired coating due to its high critical temperature and…
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…
Flux Expulsion and Material Properties of Niobium Explored in 644-650 MHz Cavities
K. McGee, S-H. Kim, P. Ostroumov +5
Upcoming projects requiring high-Q ~650 MHz medium-to-high- elliptical cavities drive a need to understand magnetic RF loss mechanisms and mitigations in greater detail. High-te…
