Description

Plasma processing is increasingly recognized as an effective technique for mitigating field emission and restoring the performance of superconducting radiofrequency (SRF) cavities. A collaboration among 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 the ongoing efforts toward implementing plasma processing both in fully assembled cryomodules and in cavities prepared for vertical testing. Here, we present the first experimental results obtained on a medium-beta 704 MHz cavity equipped with different couplers, along with preliminary investigations carried out on the high-beta 704 MHz cavity.
