Plasma Processing to Mitigate Field Emission in LCLS-II 1.3 GHz SRF Cavities
A collaboration between Fermilab, SLAC and ORNL is working to develop plasma processing for 1.3GHz TESLA shaped SRF cavities. Hydrocarbon (CxHy) contaminations and adsorbates lower the cavity surface work function (Φ) increasing Field Emission (FE). Plasma processing removes CxHy allowing the cavity to operate at higher Eacc.
