Description
The Swiss Plasma Center is proposing an upgrade to the EDIPO test facility (EDIPO 2), which will generate a 15 T background field within a 144×144 mm² aperture. This upgrade will enable variable-temperature, high-current testing of superconductor samples, enhancing the facility’s capabilities for advanced material research and development. This work presents an overview of the progress on the cryogenic system for EDIPO2.
The magnet will be cooled using a 4.2 K liquid helium bath, supplied by the facility’s existing cryoplant, which delivers supercritical helium at 4.5 K, 10 bar. The magnet mass kept at liquid helium temperature is around 20 tons and the electromagnetic stored energy is 21 MJ. The magnet will make use of the existing EDIPO vacuum vessel, and a new helium vessel has been manufactured for EDIPO 2. Detailed calculations are performed in order to assess the thermal losses through conduction, radiation, and heat exchange with surrounding components.
