    With the rapid progress of superconducting quantum computing, the cryogenic technology capable of providing appropriate cooling in the millikelvin temperature region is desirable. The cryogen-free dilution refrigerator featuring high reliability, long lifetime, and continuous cooling has become a promising cryocooler candidate.
    As one of the key components of the dilution refrigerator, the...

    The cryogen-free dilution refrigerator operating at around 10 mK or even below provides the indispensable cryogenic environment for the superconducting quantum computing, low-temperature transport property measurement and space exploration, etc. However, at extremely low temperatures, the Kapitza resistance often leads to a sharp deterioration of heat transfer in the heat exchanger and thus...

    The cryogen-free dilution refrigerator operating in the millikelvin temperature region has the advantages of no magnetic field interference, high reliability and long-term stability, which play an important role in providing the desirable cryogenic environment for the quantum computing. A cryogen-free dilution refrigerator generally operates over a broad range of temperatures, yet the large...

    Thermoacoustic machines depend on the complex relationship between thermodynamics and acoustics, and thus understanding it is vital in order to analyse the working principles and optimise parameters (i.e. geometrical or operational) to improve their performance. This paper investigates how numerical modelling can be used to explore this relationship and compares the accuracy of the performance...
