Extrapolation of the high performance JET plasmas to D-T operationFunded under: FP2-FUSION 10C
During 1989, several H-mode plasmas in JET gave a D-D fusion yield above 6 x 1.0E16 reactions/second. In order to assess the best configuration for the D-T phase of operation, the 1½-D transport code TRANSP has been used to analyse possible D-T performance for two of these shots. In the initial simulations, a D-T mixture is achieved by one of three methods: - 140 kV D beams injected into a tritium plasma - 160 kV T beams injected into a deuterium plasma - mixture of beams injected into a 50:50 D:T plasma. In the next stage of the simulations, beam power levels are increased to the predicted design values, using mixed D and T beams. It is concluded that, provided the same plasma conditions can be obtained as in the chosen pulses, fusion yields of more than 9 MW will be achieved. If the design power level for the neutral beams can be injected, this could reach 12 MW.
