Abstract
There is provided a method of reducing noise in a cryogenic cooling system associated with a mechanical refrigerator forming part of said cooling system. The method comprises: monitoring vibrations in the cooling system during operation of the mechanical refrigerator; and modulating an operating frequency of the mechanical refrigerator based on the monitored vibrations so as to reduce the amplitude of said vibrations. This allows noise within the cooling system to be reduced.
