China Makes Breakthrough in Artificial Sun Research

China's Experimental Advanced Superconducting Tokamak (EAST), the man-made sun, has made an important breakthrough by achieving an electron temperature of 100 million degrees Celsius in plasma and running under such a temperature for almost ten seconds, the EAST team announced on Monday. The research team said by using various heating techniques, the heating power reached 10 megawatts, the accumulation energy in plasma increased to 300 kilojoules and the electron temperature reached 100 million degrees Ce
