General Introduction
The High Magnetic Field Laboratory, Chinese Academy of Sciences (CHMFL) is located in Hefei, the capital city of Anhui province. Development of the lab started in May, 2008 and completed its costruction in 2017. The project includes construction of a hybrid magnet, five high power resistive magnets and four superconducting magnets. To support normal operation of these magnets, some supporting systems have been constructed for the resistive magnets: a 28MW high stability power supply, a 20 MW water-cooling system, and a central control system. A cryogenic system supplies liquid helium for the superconducting magnets, the hybrid magnet, and general experimental use. State-of-the-art measurement systems have been purchased or are being developed. When complete, CHMFL will be a National Research Center in China for multi-disciplinary studies in fixed and slowly varying high magnetic fields.  


CHMFL aims to develop and operate world-class steady high magnetic field facilities for use by in-house, national and international scientists. CHMFL research areas are condensed matter physics, nano-material fabrication and analysis, neuroscience, structural biochemistry, pharmacology, and health science. An active program of research and development will produce new magnet technologies, magnets, and instruments for unique measurements.


CHMFL is made up of four divisions: high field magnet science & technology, condensed matter science, interdisciplinary biological science, and instrument and measurement development. Every division has several subdivisions or groups, responsible for different projects.

Current Status

Three water-cooled magnets have been finished and put into service: a 10 MW magnet producing 27.5 T in a 32 mm bore, a 24 MW magnet with 35 T in a 50 mm bore, and a 25.2 MW magnet producing 38.5 T in a 32 mm bore. The final two resistive magnets, 25 T in a 50 mm bore and 20 T in a 200 mm bore, are ready for testing.

The following instruments are available for users: an 18.8 T, 54 mm bore superconducting magnet with a 950 MHz spectrometer for high-resolution NMR; a 9.4 T, 400 mm bore, high field MRI scanner, an 18 T, 52 mm cold bore magnet with installed instrumentation for scanning tunneling microscopy, magnetic microscopy, and atomic force microscopy (SMA), The hybrid magnet is still under construction. It is scheduled to be completed in the middle of 2015.

Instruments not linked to particular magnets include cryostats and probes for transport and magnetic measurements; a fast-pulse optical measurement system; a Fourier transform infrared spectrometry system; and a high pressure measurement system.

CHMFL has in total 158 employees, 21 postdocs and 102 graduated students. Quite a number of young scientists with oversea education and working experiences were recruited to CHMFL.

Scientific Research

The CHMFL in-house scientific programs has been growing in the past few years. The ongoing scientific and technical studies focus on five areas: 

· High-field magnet technology 

· Instrument and technology developments 

· Condensed matter physics 

· Material science under extreme conditions 

· Life science and biomedicine
