| Abstract: | With the wide application of high performance cryo-pump,high and low temperature superconducting devices,MRI,infrared detectors and cryogenic electronics,the development of high performance G-M cryocooler is of critical importance.In the conventional G-M cryocoolers,lead is used as the matrix material due to its specific heat is higher than many other materials in the low temperature region.However,the specific heat of lead drops rapidly below 15K,the minimum temperature achieved by the conventional G-M cry... |
