"Man-made sun" with the new "thermometer"

Has learned from hefei substance research institute of Chinese academy of sciences plasma,internationally recognized as the most accurate electron temperature and density of diagnosis system,Thomson scattering diagnosis system in our country,a new generation of"man-made sun"experiment device EAST built and debugging success.

Hefei substance research institute of Chinese academy of sciences by plasma Thomson scattering team expert introduction,at present this set of 25 Thomson scattering diagnosis system,for the most advanced domestic level,has been basically can provide plasma electron temperature and density distribution results.

Thomson scattering diagnostic system can be given in thermonuclear fusion experiments on the spatial distribution of the plasma electron temperature and density,electron temperature is internationally recognized as the most accurate measurement method,is also one of the most technically complicated several heat fusion device in the diagnosis of.Because of its importance,almost all heat fusion device developing Thomson scattering diagnostic system.

EAST core with 25 Thomson scattering diagnostic system for EAST physics,running and other calibration provide reliable diagnostic method.Engaged in nuclear fusion experimental study for 35 years,specializing in physical experiment and diagnosis technology development general atomics plasma physics experimenters Xie Zhongli professor says,the progress has not come easily.

Plasma by expert introduction,EAST core 25 Thomson diagnostic system is plasma generations of scientific and technological personnel after 10 years of effort by the phased achievements.At present the system from one of the world's most advanced level have distance,team members will continue its efforts to further improve and perfect the system.

China is the international thermonuclear experimental reactor(ITER)of one of the participating countries.In September 2006,Chinese scientists took eight years,cost 200 million yuan to EAST built and put into operation.In the first round of experiments,the scientists won the current more than 500000,nearly 5 seconds the circular cross section of high temperature plasma.EAST has become the world's first at the same time with the superconducting magnet and the structure of the active cooling nuclear fusion experimental device.It was built to make China into the advanced countries in the field of magnetic confinement fusion.
