Creating an efficient fusion plasma in a tokamak requires balancing competing temperature needs of the plasma – extremely hot in the core to allow fusion to occur but cool enough at the edge not to damage the walls of the device. Recently, China’s Experimental Superconducting Tokamaks (EAST) team from Institute of Plasma Physics (ASIPP), Hefei Institute of Physical Science (HFIPS), together with their international collaborator from DIII-D National Fusion Facility, developed an innovative solution to this challenge that uses active injection of gases to cool the plasma in the edge region of an advanced tokamak plasma, reducing the heat before it reaches the walls of the tokamak. Even better, they have done this while maintaining high plasma performance in the core region.
A roving photo exhibition organized by division of international collaboration, HFIPS was telling the stories of international cooperation of science islanders in the past decades.
A team led by Prof. WU ZHENG Yan from Institute of Intelligent Machines, Hefei Institutes of Physical Science developed a novel infrared light-responsive controlled-release pesticide system, named HCMs/IMI/PEG/α-CD, to regulate pesticide release and enhance utilization efficiency.The result was published on Agricultural and Food Chemistry.
After thousands of nuclear fusion experiments, Chinese scientists made a big breakthrough on May 28 in their quest to create an artificial sun that could help solve the world's energy problems. They set a record for sustained heat in nuclear plasma－a temperature of 120 million C for 101 seconds－said Gong Xianzu, a physicist in charge of the experiment in Hefei, Anhui province. Gong, a leading researcher at the Institute of Plasma Physics in Hefei, said on Tuesday that the result at the Experimental Advanced Superconducting Tokamak, or EAST－nicknamed the "Chinese artificial sun"－also reached a temperature of 160 million C for 20 seconds.
Thrilling games was held in the past weeks on science island. Soccer, volleyball, tennis… Horray for researchers and students on science island in this competition season.
