Role of microstructure on flux expulsion of superconducting radio frequency cavities
B. D. Khanal, S. Balachandran, S. Chetri +8
The trapped residual magnetic flux during the cool-down due to the incomplete Meissner state is a significant source of radio frequency losses in superconducting radio frequency (S…
