On July 16, 2023, Xiao Chijin, a professor and doctoral supervisor of University of Saskatchewan in Canada, came for a ten-day exchange visit. During the visit, Mr. Xiao Chijin visited the laboratory of the compact torus research group and participated in the EAST-CTI discharge test. In the test, Mr. Xiao Chijin put forward many constructive transformation plans for the compact torus discharge device, and gave solutions to the problems encountered in the test.
At 9: 00 a.m. on July 21, Mr. Xiao Chijin gave a lecture entitled “Research Progress of Compact Injection Device for Core Feeding of Fusion Reactor” in the Conference Room on the 2nd floor of EAST Control Hall. Zuo Guizhong, a researcher at the ASIPP and a division affairs member of the Tokamak Experiment Science Division, ASIPP, and Kong Defeng, head and researcher of the Scientific Development Department of the Institute of Energy of Hefei Comprehensive National Science Center, presided over the meeting. In the lecture, Mr. Xiao Chijin talked about the feasibility of feeding the compact torus core based on the principle of nuclear fusion, and focused on the principle of feeding the compact torus core and the key problems that may be encountered in the future, such as the compact torus plasma entering the tokamak core area through the drift tube and the life of CT plasma. With his rich experience and professional knowledge in the field of compact core feeding, Mr. Xiao shared his opinions and research results through vivid and easy-to-understand lectures, which brought unique perspectives and enlightenment to teachers and students.
After the lecture, the participants actively communicated with Mr. Xiao Chijin, and exchanged their own problems with Mr. Xiao, including gas valve heat measurement and plasma theoretical simulation. Mr. Xiao answered them one by one, which benefited the participants a lot.
