My primary focus is mechanical engineering with cryogenic and vacuum systems. I support multiple large projects with planning, design, fabrication and assembly. The items that I design and assemble range from large fully adjustable refrigerator stands with 6 degrees of freedom to very small precision tooling. One project that I am heavily involved with is the design and construction of cryogenic testing platforms for the Athena x-ray satellite mission. In addition, I have made significant contributions to the IARPA RAVEN project as well as the Idaho National Laboratory gamma-ray spectrometer. I track a growing list of custom designed cryogenic components and maintain detailed documentation on these parts. These documents include the manufacturing specifications for the modular TES detector packaging solution known as the microsnout. Microsnouts are currently deployed in several cryogenic systems and are planned for use with upcoming spectroscopic instruments.
