BEIJING, March 24 -- It is learned from the Hefei
Institute of Physical Science of the Chinese Academy of Sciences (CAS) on
Thursday that it has completed the first run test of the Experimental Advanced
Superconducting Tokamak (EAST) which aims to explore infinite and clean energy
resources of nuclear fusion 2006.
The focal parts
-- low temperature and magnet electricity conducting, have passed the test,
which makes a strong basis for the use of nuclear fusion within this year. By
then, the institute will be the first in the world to have built an
all-superconducting non-circular section nuclear fusion experiment
facility, generally known as an artificial sun.

The energy resource crisis has begun to threaten the
world, as oil, coal and other types of non-renewable energy resources will be
used up in a century. Scientists recommend the extraction of deuterium from sea
water and the ignition of nuclear fusion of this element in temperatures as high
as 100 million degrees Celsius. In nuclear fusion, deuterium abstracted from one
kilogram of sea water will be able to produce as much energy as that of 300
liters of gasoline.
Invention of a facility that can withstand the
temperature of 100 million degrees Celsius and control deuterium and atomic
fusion to ensure steady and continuous energy output is equal to invention of an
artificial sun, which can provide infinite and clean energy like the sun, as sea
water is virtually inexhaustible.
In 1990, the CAS Institute of Plasma Physics built
China's first superconducting tokamak equipment HT-7, making China the fourth
country in the world to have such equipment after Russia, France and Japan. In
2000, scientists at this institute began to build a new-generation
all-superconducting non-circular section tokamak equipment on the basis of HT-7
and gave it the new name EAST.
As an upgraded product of HT-7, EAST brings China
into the globally leading group in nuclear fusion research. It is also a key
project of China's ninth five-year-plan. EAST started overall assembly in
