Dr. Ryan Snodgrass leads the Cryocoolers Team within the Quantum Sensors Division. The Cryocoolers Team aims to make 4 kelvin and below cryogenic refrigerators more accessible through thermoacoustic analysis and proof-of-principle experiments. Ryan is particularly interested in improving the efficiency of cryogenic refrigerators, since this efficiency determines the infrastructure required to perform much low-temperature science. Recent projects of the Cryocoolers Team include methods for rapid cooldown of pulse tube refrigerators, exergy analysis of scroll compressors and cryocooler valves, detailed studies of regenerator cooling in cryocoolers operating near 4 kelvin, and thermodynamic analysis of miniature dilution refrigerators that circulate helium-3 using cold adsorption pumps.
