This report details the mechanism design and heat load budget for a cryostat that replace liquid helium and liquid nitrogen with commercially available cold heads (cryocoolers). However, to ensure the proper functioning of cryogenic superconducting magnets with the limited cooling capacity of cryocoolers, careful management of heat transfer, insulation, cooling, electrical power, and vacuum...
Magnet Cold Test Bench (MCTB) is a test facility under development to test the superconducting Toroidal Field (TF) and Poloidal Field (PF-1) magnets at ITER. The testing of the magnets will be performed at 4K cryogenic temperature. The cryostat is required for housing the TF and PF-1 magnets in the vacuum environment for test at cryogenic temperature.
The material of construction for the...
In the framework of the Future Circular Collider (FCC) study at CERN, a conceptual design of a cooling scheme for Nb$_3$Sn-based accelerator magnets operating at 4.5 K is proposed for the FCC-hh (hadron) configuration. This alternative, at a higher operating temperature than the baseline at 1.9 K using Helium II, is motivated by a strong commitment to a more energetically...
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...
Multi-Layer Insulation (MLI) is widely used in cryogenic systems to effectively suppress radiation due to temperature differences. In particular, MLI plays a crucial role in reducing cooling energy consumption and maintaining the thermal stability of superconducting coils in superconducting magnet systems. High-field superconducting magnets require cryogenic environments to sustain high...
Several new controlled nuclear fusion systems are under development in China. To achieve the higher magnetic field intensity and to minimize the final size as well, the high-Tc superconducting magnets are adopted. There are a variety of rigorous requirements on the associated cryogenic system expected to provide 600 W at around 20 K, of which high-efficiency and high-reliability are especially...
A demonstrative NbTi based Mixed Axial and Radial field System (MARS-D) is being developed for a next-Generation Electron Cyclotron Resonance Ion Source (ECRIS) at Lawrence Berkeley National Laboratory, which employs a novel closed-loop coil design scheme that more efficiently utilizes conductor fields and extend the application of NbTi for high frequency (up to 45 GHz) ECR operation. The NbTi...
Superconducting magnets serve as pivotal components in advanced rail transportation, next-generation power systems, Magnetic Confinement Fusion, and other critical infrastructure. They find extensive applications across various sectors including industry, energy, medicine, large scientific apparatuses, and semiconductors. Superconducting magnets are typically cooled through coolant immersion...
