Abstract
A cryogenic cooling system comprises a dilution refrigerator with a mixing chamber (401), a still (402), and a circulation arrangement for circulating working fluid through said mixing chamber (401) and still (402). At least one active heat exchanger (408, 801, 802, 901) has a first end and a second end and that is configured to use input energy to transfer heat from the first end to the second end during operation. Said first and second ends of the at least one active heat exchanger (408, 801, 802, 901) are thermally coupled to respective positions along said circulation arrangement for transferring heat between respective portions of the circulated working fluid.
