Further, the results are anticipated to be beneficial in improving plasma not only in helical devices such as LHD, but also in tokamaks as represented by the International Thermonuclear Experimental Reactor (ITER), which is currently under construction. (sciencedaily.com)
Fortunately, ongoing research programs are revealing ways to improve substantially the performance of tokamak reactors. (scientificamerican.com)
There is no longer any question of its scientific feasibility: near breakeven (the state at which the fusion power produced equals the power consumed to sustain the plasma) has been demonstrated with actual fusion fuels in Princeton's nearly 20 - year - old Tokamak Fusion Test Reactor (TFTR).
