Cooling and packaging of RF components

    Research output: Chapter in Book/Report/Conference proceedingChapterAcademicpeer-review


    The ideal cryogenic refrigerator (“cryocooler” or “cooler”) for cooling superconducting RF components should have a cooling power of a few Watts at the desired operating temperature, with an input power of also only a few Watts. Furthermore, it would be nice if it had infinite operating lifetime and costs only a few dollars. More wishes can be made, but it is obviously clear that such an ideal cooler, unfortunately, does not exist. Therefore, in the design of the complete system, a trade-off has to be made to compromise these wishes or requirements. In this trade-off process, device design and cryopackaging design have to interact. For example, a lower operating temperature may be desirable from the point of view of device performance while a lower temperature will necessitate a cooler that is bigger, heavier and more expensive. In this chapter, the cryopackaging aspects are considered. The main questions to be answered are:
    How do available coolers work?
    What are trends in cooling
    What are the important aspects in packaging?
