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…
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…
Evaluation of predictive correlation between flux expulsion and grain growth for superconducting radio frequency cavities
