Title: Plasma Processing to Mitigate Field Emission in LCLS-II 1.3 GHz SRF Cavities

Abstract

A collaboration between Fermilab, SLAC and ORNL is working to develop plasma processing for 1.3GHz TESLA shaped SRF cavities. Hydrocarbon contaminations and adsorbates lower the cavity surface work function increasing Field Emission (FE). Plasma processing removes the hydrocarbon allowing the cavity to operate at higher Eacc. Here are presented the results obtained at Fermilab regarding a new method of ignition developed for 1.3GHz cavities and the application of plasma processing to contaminated single cell and 9-cell cavities.
