Designing a High Pressure Rinse Mount for Superconducting Material Samples

Superconducting radio frequency (SRF) cavities, used to accelerate a charged particle beam, are one of the vital organs of an accelerator --- improving their performance allows for higher beam energies, which opens new frontiers in various branches of science and medicine. The material properties of the superconductors used to make these SRF cavities are one of the major factors in determining how well they will perform in an actual accelerating structure. The Cornell High Pulsed Power Sample Host Cavity (CHPPSHC) is a system recently commissioned by our research group. Its purpose is to test the material limits of candidate SRF materials with samples. These samples must be extremely clean before they can be assembled into the sample host cavity. Typically, we use a high pressure rinser with high purity de-ionized water to clean accelerating cavities. This particular sample geometry could not be accommodated by our system without design and fabrication of a new mount. In this paper I introduce this new mount along with considerations that went into its design.
