摘要
The problem of plasma detachment as a means to reduce the power load onto divertor targets has been studied numerically for the JET MkI divertor. In particular the dependence of detachment on mid-plane separatrix density, power entering the SOL and impurity radiation has been examined. It results that the problem of power exhaust in ITER relevant plasmas is likely to require dissipation of a non-negligible amount of power (greater than or equal to 50%) by means of impurity radiation, thus linking the problem of power exhaust to that of controlling a properly chosen injected impurity.
