Description
Plasma processing is increasingly recognized as an effective technique for mitigating field emission and restoring the performance of SRF cavities. A collaboration between CEA, ESS and INFN is currently working to adapt and optimize this method for the medium- and high-beta elliptical cavities installed in the ESS linac.
This contribution summarizes ongoing efforts to implement plasma processing both in cavities assembled in cryomodules and in cavities prepared for vertical testing. The work presents electromagnetic analyses performed to identify the modes that best allow processing of the cavities, together with the conceptual design of the vacuum system for the experimental setup. Results obtained on a 704 MHz medium-beta cavity equipped with different couplers are also reported, along with preliminary investigations carried out on the 704 MHz high-beta cavity.
