ABSTRACT:
Through a long relentless search for the fusion energy, International Thermonuclear Experimental Reactor (ITER) project sponsored by the consortium of seven countries is officially launched and will decisively demonstrate a feasibility of the future energy source for human kinds. Intensive physics
research from the large tokamak devices (JET, TFTR, and JT-60), which have routinely illustratedScientific Break-even?condition (~20keV; optimum cross-section for DT) well justifies the ITER project. Significant increase of the participating countries from Asia (Korea, China, India, and Japan )
is mainly driven bythe necessity of the precious new energy resource. At the same time, it reflects the paradigm change of the fusion plasma research which once was dominated by advanced countries(US and EU and JP). However, a long sustainment of the magnetically confined hot plasmasin steady state is still a challenging physics problem beside theengineering issues to be resolvedin the future. New approach of the physics study is essential so that the transient high beta plasmas achieved in previous generation tokamak can be extended to the steady state operation in the new superconducting tokamak devices such as KSTAR, EAST, SST and JT-60SA in Asia. Successful test of the new physics on these devices will increase the chance of the success of the ITER project as well as the understanding of the fundamental physics of high temperature plasmas in the magnetic field.
