Narrow bandwidth active noise control for microphonics rejection in superconducting cavities at LCLS-II
Andrea Bellandi, Julien Branlard, Jorge Diaz Cruz +9
LCLS-II is an X-Ray Free Electron Laser (XFEL) commissioned in 2022, being the first Continuous Wave (CW) hard XFEL in the world to come into operation. To accelerate the electron…
Plasma Processing for In-Situ Field Emission Mitigation of Superconducting Radiofrequency (SRF) Cryomodules
M. Martinello, P. Berrutti, B. Giaccone +14
Field emission (FE) is one of the main limiting factors of superconducting radio-frequency (SRF) cavities operating in accelerators and it occurs whenever contaminants, like dust,…
LCLS-II-HE verification cryomodule high gradient performance and quench behavior
S. Posen, A. Cravatta, M. Checchin +43
An 8-cavity, 1.3 GHz, LCLS-II-HE cryomodule was assembled and tested at Fermilab to verify performance before the start of production. Its cavities were processed with a novel nitr…
Low RF power plasma ignition and detection for in-situ cleaning of 1.3 GHz 9-cell cavities
P. Berrutti, B. Giaccone, M. Martinello +7
Superconducting Radio Frequency (SRF) cavities performance preservation is crucial, from vertical test to accelerator operation. Field Emission (FE) is still one of the performance…
