When NIST researchers took a closer look at the pulse tube refrigerator – commonly used in both research and industry and capable of achieving temperatures as cold as the vacuum of outer space – they found that manufacturers had built the device to be energy efficient only at its final operating temperature of 4 kelvin (K). The team found that the efficiency of the refrigerator could be greatly improved if they continually adjusted a series of valves that control the amount of helium gas flowing from the compressor to the refrigerator. This modification reduces the time and energy required to chill materials to temperatures near absolute zero and will benefit quantum computing, astronomy, superconductors and much more.
