Continuous-Wave Operation at 30 MV/m of a Superconducting Radio-Frequency Gun Cryomodule with an Exchangeable Cathode Plug
T. Konomi, T. Xu, Y. Choi +30
A prototype 185.7 MHz superconducting radio-frequency (SRF) electron gun cryomodule has been developed for the proposed LCLS-II-HE Low Emittance Injector at SLAC. It has an in-situ…
Multipacting Processing in Cryomodules For LCLS-II And LCLS-II-HE
A. Cravatta, T. Arkan, D. Bafia +12
Multipacting (MP) is a phenomenon which can affect stability in particle accelerators and limit performance in superconducting radio frequency cavities. In the TESLA shaped, 1.3 GH…
Electrochemical Polishing of Chemical Vapor Deposited Niobium Thin Films
Zeming Sun, Mingqi Ge, James T. Maniscalco +3
Combining chemical vapor deposition (CVD) with electrochemical polish (EP) operations is a promising route to producing performance-capable superconducting films for use in the fab…
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,…
Plasma Cleaning of LCLS-II-HE verification cryomodule cavities
Bianca Giaccone, Paolo Berrutti, Martina Martinello +14
Plasma cleaning is a technique that can be applied in superconducting radio-frequency (SRF) cavities in situ in cryomodules in order to decrease their level of field emission. We d…
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…
Effects of Interstitial Oxygen and Carbon on Niobium Superconducting Cavities
P. N. Koufalis, D. L. Hall, M. Liepe +1
We present results on the effects of interstitial oxygen and carbon on a bulk-niobium superconducting radio-frequency cavity. Previous experiments have shown that high-temperature…
The Importance of the Electron Mean Free Path for Superconducting RF Cavities
J. T. Maniscalco, D. Gonnella, M. Liepe
Impurity-doping is an exciting new technology in the field of SRF, producing cavities with record-high quality factor and BCS surface resistance that decreases with increasin…
