Cooling Methods for HTS Applications - Challenges and Approaches

In cryotechnology there is a deep expertise in removing heat at low temperatures and avoiding heat loads from the environment. HTS applications at low temperatures (and sometimes high magnetic field) strongly benefit from that. Nevertheless, an increasing number of HTS devices is operated at elevated, but still cryogenic temperatures. These devices put some additional requirements on the cooling technology (e.g. higher heat load from the environment, ac-operation, voltages, etc.). In this ballpark, the cooling concept and the HTS device are strongly interplaying.
In this presentation, we will discuss selected HTS applications and cooling concepts, and how the challenges of restrictions and opportunities might benefit from specific adoption of cooling method and application.
