D-D fusion reactivity studies in high temperature JET plasmas
The D-D fusion reactivity from JET plasmas has been optimised by using combined NBI and RF heating. Reaction rates of up to 2.9 x 1.0 E16 reactions/s are achieved. The best results are obtained in the double null magnetic configuration or with plasmas limited by the inner wall. By far the largest fraction of the neutron production originates from beam induced reactions, although, in some cases, about 25% of the production can be attributed to beam acceleration by the RF. The instantaneous neutron yield is limited by a strong influx of carbon impurity ions due to excessive, but local, wall heating.
