摘要

Fusion is an ideal clean energy for human beings in the future.Significant progress has been achieved on tokamak research after successful construction of many large tokamak facilities and many years of experiments, which have established a sound base for tokamak experimental reactors.More than 10 MW fusion power has been produced in the Tokamak Fusion Testing Reactor (TFTR) [1] and Joint European Torus (JET) [2] tokamaks.An equivalent Q (Q =output fusion power/input extemal heating power) of over unity was reached in the JT-60U [3] device during the last century.Since 2000, world tokamak research has moved to the new generation of fully superconducting tokamaks for steady-state high-performance operation.The Experimental Advanced Superconducting Tokamak (EAST) [4] and Korean Superconducting Tokamak Advanced Research (KSTAR) [5] tokamaks have been built and very good progress has been made.Tokamak research has reached a new era with joint efforts from China, Europe, India, Japan, Korea, Russia and the USA to build the International Thermonuclear Experimental Reactor (ITER) [6].ITER will bring tokamak fusion research to a state where burning plasma, in which alpha partide self-heating will be dominant, can be explored.Over the coming 10 years, the world fusion community will make joint efforts to finish the ITER construction and start scientific experiments.Meanwhile, most of the ITER party has its own strategic plan to approach the Demonstration (DEMO) fusion reactor and efforts have been made in this direction.
