Bold Visions in Educational Researchmust not only be low cost, but also have long life and high reliability. Over the past two years Superconductor Technologies Inc. (STI) has integrated a new cryocooler design into our commercial HTS systems. This cooler is an improvement over the previous cooler we were using in this application how

Awakening Mindfulness in Science Educationment. Its performance is 6 W at 70 K with 150 W input under 23°C ambient conditions; at 50°C ambient, it produces 5 W at 70 K with 150 W consumption. The mean time before failure for the design is over 40,000 hours. Flexure springs are used to support the compressor cylinders and the displacer in th

Małgorzata Powietrzyńska,Kenneth Tobinsertion of this technology into coolers intended for tactical or commercial application has been slow due to cost considerations. This paper describes the development and testing of a flexure spring system for small tactical cryocoolers that provides a doubling of operating life while costing approx

What is God? Between Texts and Mogra Trees,ation systems. In July 1999, we reported on our development of a 5 W Stirling pulse tube cryocooler with a contact-type compressor,. with a cooling capacity of 5.5 W at 80 K for 200 W of input power. However, demands for a smaller-sized cryocooler with higher efficiency and with 5-year reliability p

Its performance is greater than that of an LGE water-cooled PTC of last year, 4.9 W at 65 K and 20°C, with 270 W of input power. The air-cooled PTC, compared to the water-cooled one, has a lower-efficiency linear mo

Leonardo Gabrielli,Stefano SquartiniInternational Space Station is scheduled for 2003. The basis for the cooler development is the AIM model SL200 cooler; it has a nominal cooling capacity of 3.5 W at 77 K, and is used for cooling high performance IR detectors. The space mission will have a duration of three years with two years in op
