The Magnet Technology Group (MTG) is dedicated to supporting national major science and technology infrastructure construction and frontier physics research. It focuses on key technical fields including room-temperature resistive magnets, low-temperature superconducting magnets, high-voltage electrostatic deflection systems, and advanced magnetometry. MTG aims to build a core technical team characterized by "technological innovation leadership, outstanding engineering capabilities, and a global perspective," providing full-lifecycle magnet technology support for major scientific facilities such as HIAF and CiADS, addressing core challenges in future advanced accelerator magnets, and emerging as an internationally advanced base for accelerator magnet technology R&D, engineering application, and talent cultivation.

MTG currently has over 30 staff and several students, with established laboratories for the development and testing of room-temperature/superconducting magnets and high-voltage components (e.g., electrostatic deflection plates).

In recent years, MTG has undertaken and completed numerous research projects, including national major science and technology infrastructure projects, National 973 Program, CAS key projects, and general/young scientist projects of the National Natural Science Foundation of China (NSFC). These include magnet systems for national scientific facilities (HIRFL, HIMM, HIAF, ADS), magnet systems for SESRI and PREF, the high-field Nb₃Sn ECR ion source magnet for the NSFC major instrument project LEAF, high-field fast-cycling superconducting magnets under the Ministry of Science and Technology's Key R&D Program, as well as SECRAL-II and Lanzhou Penning Trap.

MTG has also participated in international cooperation projects, such as the design and testing of room-temperature magnets and superconducting solenoids for FRIB, the development of Super-FRS superconducting dipole magnet prototypes for FAIR, the prototype development and batch low-temperature testing of CCT superconducting dipole corrector magnets for the LHC High-Luminosity Upgrade, and high-field fast-ramped dipole magnets. Domestically, MTD has conducted extensive and in-depth cooperation with universities and research institutes including Peking University, Tsinghua University, Lanzhou University, and Shanghai Institute of Applied Physics, accumulating rich experience in magnet development through these projects.

Currently, MTG is undertaking projects such as the room-temperature and superconducting magnet systems for the China initiative Accelerator Driven System (CiADS), the large-aperture superconducting dipole spectrometer magnet for the NSFC major instrument project CEE, the new-generation medical heavy-ion accelerator therapy system (SIMM), the accelerator-based medical isotope R&D platform (IP-SAFE), and the upgrade projects of magnet systems for HIRFL and HIAF.

Future Technology Development Plan

MTG will focus on technical directions including high field, fast ramping, green technology, high precision, radiation resistance, and liquid-helium-free operation. It will conduct R&D and engineering of superconducting magnets, room-temperature magnets, high-voltage electrostatic deflection systems, advanced magnetometry, and new materials/processes to form independent core intellectual property rights.

Platform Construction

MTG will improve professional laboratories and testing equipment systems, establish a full-chain technical platform covering magnet design, fabrication, testing, and validation, formulate magnet process standards and quality control systems, and strengthen the implementation of safety regulations to ensure technical and engineering quality.

Talent Development and Cooperation

MTG is committed to cultivating interdisciplinary talents with both academic literacy and engineering capabilities, deepening domestic and international academic exchanges and technical cooperation, promoting the transfer of magnet technology to fields such as isotope production and medical equipment.

Design and development of room-temperature resistive magnets, design and development of superconducting magnets, research on cryostat systems and advanced magnetic field measurement technologies, covering interdisciplinary fields including physics, mechanical engineering, cryogenics, automation, and software engineering.

MTD has accumulated 146 high-quality papers (over 90% being SCI-indexed), 46 authorized invention patents, and 2 software copyrights. It has formulated multiple magnet process and quality specifications, with technologies enabling applications in isotope production, medical equipment, and other fields.
