Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP) was founded

in Sept. 1978 in Hefei, China. The institute has more than 1000 staffs,

distributed in 13 research divisions, 2 technical centers and 4 high-tech

companies.

Significant progress of fusion technology has been

made since China joint ITER.

EAST starts high performance physics experiments

and stationary H-mode was obtained.

CFETR will benefit from ITER and make joint

efforts towards DEMO.

Worldwide team work is our future, we are looking

forward for your contribution.
