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,…
Achievement of Ultra-High Quality Factor in Prototype Cryomodule for LCLS-II
G. Wu, A. Grassellino, E. Harms +4
Quality factor is a primary cost driver for high energy, continuous wave (CW) SRF linacs like the LCLS-II X-ray free electron laser currently under construction. Taking this into a…
The Role of Magnetic Flux Expulsion to Reach Q0>3x10^10 in SRF Cryomodules
S. Posen, G. Wu, E. Harms +7
When a superconducting radiofrequency cavity is cooled through its critical temperature, ambient magnetic flux can become "frozen in" to the superconductor, resulting in degradatio…
A gap clearing kicker for Main Injector
I. Kourbanis, P. Adamson, J. Biggs +10
Fermilab Main Injector has been operating at high Beam Power levels since 2008 when multi-batch slip stacking became operational. In order to maintain and increase the beam power l…
Investigations of surface quality and SRF cavity performance
G. Wu, M. Ge, P. Kneisel +4
Magnetic field enhancement has been studied in the past through replica and cavity cutting. Considerable progress of niobium cavity manufacturing and processing has been made since…
