Abstract :
Los Alamos completed the R&D program for the SNS linac in September 2002 with publication of a comprehensive report on the SNS coupled-cavity linac (CCL) hot model. In this paper we summarize the results of this R&D program, including design of the bridge-coupled CCL, refinement of the design through cold models, and fabrication and testing of a hot model. We describe the RF system used to power the model, the prototype water-cooling and vacuum systems, and the experimental tests of these systems, including low-power, high-power, and radiation measurements. The CCL hot-model experiments answered vital questions about design, manufacturability, and stability for this type of RF structure.
