Research activities:
(1) Design and construction of HT-7U Superconducting Tokamak, to be finished around 2003. Its scientific mission is 1) to realize tokamak steady-state operation; 2) to improve plasma confinement, increase with steady-state operation; 3) to perform heat and particle flow control. Our ultimate aim is to realize steady state operation with advanced tokamak mode on HT-7U with superconducting toroidal field (TF) and poloidal field (PF) and explore the approach to magnetic confined fusion energy.

(2) High temperature plasma physics (experiments and theory), energy and particle transport, confinement, MHD instabilities, plasma-wall interaction, plasma-microwave interaction, lower hybrid current driven plasma discharges, influence of helical windings on plasma performance, impurity behaviour in tokamaks, quasi steady-state plasma performance.

(3) Other fusion related technology, e.g. pulsed huge electrical power supply, megawatt ICRH microwave power supply and radiator, megawatt LHCD microwave power supply and radiator, plasma diagnostics.

The main research facilities are: the HT-6M tokamak (R=65cm, a=20cm, Bt=15kG, Ip=150kA), the HT-7 superconductive tokamak (R=122cm, a=35cm, Bt=30kG, Ip=400kA) with a 300 L=hr liquid helium and a 600 L=hr liquid nitrogen cryogenic station, an AC flywheel motor-generator set of 120 MW, four sets of DC flywheel motor generators with a total power of 80 MW, a 1 MW ICRH system and a 400 kW LHCD system. Another 1 MW ICRH system and a 2 MW LHCD system are under construction, a 20 Tesla steady-state Hybrid High Field Magnet with other water-cooled, superconducting and pulsed magnets.

The HT-7U superconducting Tokamak is under construction. Its main parameters are: Toroidal Field, Bo=3.5T, Plasma Current, IP=0.5MA, Major Radius, Ro=1.7m, Minor Radius, a=0.4m, Aspect Ratio, R/a=4.25, Elongation, Kx=1.6 - 2, Triangularity, dx=0.6 - 0.8, Heating and Driving: ICRH=3MW, LHCD=4MW, ECRH=0.5MW, NBI = Non (5MW on the second stage), Pulse length = 1-1000s, Configuration: Double-null divertor, Single null divertor.
