Description
The cooling of large superconducting detector magnets used in high-energy physics relies on a continuous supply of liquid cryogen that is provided by large and complex cryogenic plants. An alternative to this is the development of cooling systems based on the use of cryocoolers. Such a solution can be employed to cool a superconducting magnet itself or to intercept heat from other components of the magnet cryostat.
One of the major sources of heat load for detector magnets is current leads. This study aims to develop and test gas-cooled High-Temperature Superconducting current leads for a Low-Temperature Superconducting detector magnet with an operating current of 3kA along with the associated cryogenic assembly. The heat load coming from the room temperature is intercepted at 50K by using helium circulating in the closed loop that consists of a single-stage Gifford-McMahon cryocooler, cold circulator and dedicated heat exchangers. An overview of the design and optimization efforts will be presented. The test setup for the demonstrator is currently under construction and the first experimental results are expected by the end of 2024.
