Improving Sorption Compressors for Cryogenic Cooling

Coolers that consist of a sorption compressor with a Linde-Hampson (LH) cold stage are thermally driven and have no moving parts, apart from some check valves. As a consequence, they can be scaled to small sizes, can operate with an absolute minimum vibration level and wear-related issues hardly play a role, giving the potential for a long cooler lifetime. As a result, sorption cooling was considered an attractive option to be used for cooling a superconducting AD-convertor. As part of the thesis work, the cooling options were explored of such a convertor consisting of a high-Tc superconducting digitiser and semiconductor electronics to decimate and further process the data.
