The physics of an ignited tokamak
A Next Step device which can demonstrate long burn with a high probability of success is possible, without speculating on the accumulation of favourable effects and ignoring others. From the data available this appears possible only with large devices such as NET, ITER or JIT. If such a device is to provide the necessary database to go to DEMO, it must be able to explore a sufficiently wide range of parameters. From present knowledge, this can be obtained by choosing a conservative value of the reference magnetic field away from technological limits and compensating with a larger size. There remain for all devices very serious physics problems to solve, the most acute being the exhaust, which must be compatible with a good quality enhanced confinement regime and a sufficiently high wall load to make a reactor.
