TL;DR: The Thomas Jefferson National Accelerator Facility (CEBAF) as discussed by the authors has begun a cryomodule refurbishment project, which includes reprocessing of SRF cavities to eliminate field emission and increase the nominal gradient from the original 5 MV/m to 12.5 M/m. The goal of this project is robust 6 GeV, 5 pass operation of the CEBAF.
