High-Frequency Cryocooler Is Tiny, Cold and Efficient

A new cryogenic refrigerator has been demonstrated at the National Institute of Standards and Technology that operates at twice the usual frequency, achieving a long-sought combination of small size, rapid cooling, low temperatures and high efficiency. The cryocoooler could be used to chill instruments for space and military applications, and is a significant step toward even smaller, higher-frequency versions for integrated circuits and microelectromechanical (MEM) systems.
