Chinese achievements in the A3 program

The implementation process focused on the international frontier requirements of the subjects and followed a goal-limitation and key-breakthrough principle based on the domestic existing foundation. Great importance was attached on the combination between theoretical and numerical simulation and physical experiment research. Enthusiasm and specialty were fully stimulated in domestic partners by cooperating closely with the scientists of other universities and research institutes to improve physical research level, share joint research results, and successfully complete the planned tasks. Following research work has been mainly carried out: 1) Experimental research of steady-state discharge of high-performance plasma; 2) A variety of lithium wall processing and recycling control technology; 3) Edge localized modes (ELM) mitigation; 4) Mechanism research of the L-H transition physics; 5) Current drive and profile control; 6) MHD instability and its dynamics; 7) Experimental and theoretical research of high-energy runaway electron dynamics.
