Advances in fusion research on magnetic plasma confinement
The research described here is concerned with achieving a positive balance of performance in a fusion reactor, for which it is necessary to confine a very hot plasma for long enough within a magnetic field to compensate for the unavoidable loss of heat and energy by radiation. The stellarator and tokamak toroidal magnetic field configurations are particularly suited to this purpose. The milestones of progress and problem areas are detailed. It is now necessary to develop a new experimental reactor in which the issues of transferability to future large-scale experiments and the maintenance of burning fusion plasma will play a significant part. Although the stellarator principle offers many advantages because of the current-free toroidal confinement, NET, the European project, and ITER, the international project, are based on the tokamak principle, since the best results have so far been achieved with this. It is possible that the reactor technology developed with ITER could be transferred to the stellarator. In order to make further advances in the field of fusion, ITER has been decided upon, which means that the financial risk will be distributed among very many nations.
