Title Development of Helium Vessel Welding Process for SNS PPU Cavities
Abstract The Spallation Neutron Source Proton Power Up-grade cavities are produced by Research Instrument with all the cavity processing done at vendor sites with final chemistry applied to the cavity to be electropolishing. Cavities are delivered to Jefferson Lab, ready to be test-ed. One of the tasks to be completed before the arrival of production ready PPU cavities is to develop a robust helium vessel welding protocol. We have successfully developed the process and applied to three six cell high beta cavities. Here, we present the summary of RF re-sults, welding process development and post helium vessel RF results.
