Brief Introduction

The Magnet Technology Group (MTG) is mainly responsible for the technical support and R&D (research and development) of magnets (Room temperature and superconducting)  for the existing and future particle accelerators. MTG also provide high class magnets design, R&D and testing services for various particle accelerators, scientific research and experimental terminals. At present, there are 30 full-time employees and 5 students, including 3 with senior titles and 11 with vice-senior titles. The team of MTG has the capability of simulation and design of various kinds of magnets, meanwhile, fully equipped laboratory has been established for the magnetic field measurement and high-voltage components test. 

The MTG has very good research foundations and project experience. From the beginning of the establishment to now, it has undertaken and completed a number of scientific research tasks which include Major State Basic Research Development Program of China (973) projects, the major subject of the Chinese Academy of Sciences, and NSFC projects etc., such as magnet systems for HIRFL-CSR, HIMM, ADS, SECRAL-II, and Lanzhou Penning ion trap. MTG has also been involved in many international cooperation projects, such as FRIB (USA) and FAIR. We have established extensive cooperative relations with many domestic research institutes and Universities, such as Peking University, Tsinghua University, Lanzhou University IHEP (Institute of High Energy Physics, Chinese Academy of Sciences) and SINAP (Shanghai Institute of Applied Physics, Chinese Academy of Sciences) 

At present, MTG is undertaking the R&D work for many projects, including the magnet systems for three major science and technology infrastructure projects—HIAF, CiADS and SESRI, and two Major research instrument development projects of NSFC-LEAF and CEE et al. Meanwhile, the project of upgrading the magnet system for HIRFL is in progress.
