Sage software was used to design the pulse tube, with a predicted 25 W of cooling power at 50 K, and an input indicated power of 1.7 kW. The fabricated pulse tube is closely coupled to a metallic diaphragm compressor (pressure wave generator) with a 60 ml swept volume, operating at 50 Hz, and with a mean helium working gas pressure of 25 bar. Details of the development, experimental results and correlations to the Sage model are discussed.Generally, items in SMARTech are open to the public. However, there are instances where copyright law or specific needs of the depositor requires campus-only access. The Library always encourages open access to all items found in SMARTech but will review requests for limited, campus-only access on a case by case basis.High-capacity 50-80 k single-stage cryocoolersHigh frequency single-stage coaxial pulse tube cryocoolersDiaphragm compressorsPressure wave generatorsMean gas pressureConference ContributionOpenAccess
