Excellent performance of 650 MHz single-cell niobium cavity after electropolishing
V. Chouhan, D. Bice, A. Cravatta +6
Electropolishing process and cathodes have undergone modification and optimization for both low- and high-beta 650 MHz five-cell niobium cavities for PIP-II. Cavities treated with…
Latest Development of Electropolishing Optimization for 650 MHz Niobium Cavity
V. Chouhan, D. Bice, D. Burk +15
Electropolishing (EP) of 1.3 GHz niobium superconducting RF cavities is conducted to achieve a desired smooth and contaminant-free surface that yields good RF performance. Achievin…
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…
