During the second half of 1997, JET carried out a broad-based series of experiments in deuterium-tritium (D-T) producing a total of 675 MJ of fusion energy and setting records for fusion power (16MW), ration of fusion power to plasma input power and fusion power duration. A large scale tritium supply and processing plant, the first of its kind, allowed the repeated use of the 20g tritium on site, supplying a total of 99.3g of tritium to the machine.

The D-T physics programme allowed the size, heating requirements and operating conditions of the International Thermonuclear Experimental Reactor to be defined more precisely. The threshold power required to access the high confinement operating mode foreseen for ITER is significantly lower in D-T than in deuterium but the global energy confinement time itself is practically unchanged. ITER demonstration pulses, in which the important dimensionless parameters for confinement were matched to those of ITER, predict ignition for ITER provided the required densities can be reached. Three radio frequency schemes for heating ITER were also tested successfully in D-T. .
