Core Viewpoint - The successful development of a fully superconducting user magnet with a peak magnetic field strength of 35.6 Tesla marks a significant advancement for China in high-temperature superconducting applications, establishing international leadership in this field and providing technical support for material science, life sciences, and nuclear fusion research [1][3]. Group 1 - The fully superconducting user magnet, featuring a core of high-temperature superconducting insert magnets, has a diameter of 35 millimeters and achieved a magnetic field strength of 30 Tesla in 2023, now offering capabilities above 30 Tesla to domestic and international users [3]. - Continuous upgrades to the materials, structure, and processes of the device have enabled the achievement of the 35.6 Tesla peak magnetic field strength while maintaining the same diameter, making it the only fully superconducting user magnet globally capable of providing over 30 Tesla in the field of material science research [3]. Group 2 - The fully superconducting user magnet is constructed within the Comprehensive Extreme Conditions Experimental Facility located in Beijing Huairou Science City, which is set to pass national acceptance in February 2025 [5]. - This facility integrates extreme low temperatures, strong magnetic fields, ultra-high pressure, and ultra-fast light fields, with the 35.6 Tesla superconducting user magnet providing robust technical support for researchers exploring the microscopic world of materials [5].
