Publication Abstract: | The Proton Power Upgrade project at Oak Ridge National Lab?s Spallation Neutron Source (SNS PPU) currently being constructed will double the proton beam power from 1.4 to 2.8 MW by adding 7 additional cryomodules, each contains four six-cell high beta (beta = 0.81) superconducting radio frequency cavities. The cavities were built by RI, with all the cavity processing done at the vendor site, including electropolishing as the final active chemistry step. All 28 cavities needed for 7 cryomodules were delivered to Jefferson Lab, ready to be tested. The RF qualifications and HV vessel welding were done at Jefferson Lab. Performance largely exceed requirements, and greatly exceeded the performance of the original SNS cavity production series. Here, we present the summary of RF test on production cavities to this date. |
