Report on first plasma processing trial for a FRIB quarter-wave resonator cryomodule
Walter Hartung, Wei Chang, Yoo-Lim Cheon +6
Plasma processing has been shown to help mitigate degradation of the performance of superconducting radio-frequency cavities, providing an alternative to removal of cryomodules fro…
