China introduces ‘Artificial Sun’
Hefei Institute of Physical Science of the Chinese Academy of Science has come up with a new artificial sun experiment.
The researchers have successfully realised Ultra High Temperature long pulse plasma discharge at any temperature more than 50 million degrees.
As of January, the Experimental Advanced Superconducting Tokamak (EAST) fusion device, nicknamed “artificial sun”, created a 102-second-long pulse plasma discharge at a central electron temperature of 50 million degrees-plus, the People’s Daily reported.
“An artificial sun can provide limitless clean energy through controlled thermonuclear fusion,” said Xu Jiannan, a Chinese researcher at the Academy.
The light and heat of the sun come from deuterium and tritium which are the isotopes of hydrogen. These release a huge amount of energy during the process of fusion into a helium atom. The artificial sun imitates this fusion process.
According to Xu, the academy and the Shanghai Institute of Optics and Fine Mechanics (SIOM) have established an independent study on inertial confinement fusion and also developed laser driving devices as well as a PTS device. The output current of the PTS device reaches a level of 8 to 10 million Ampere.
