An account is given of the high performance plasmas established by development of the H-mode regime in JET in the experimental campaigns up to 1992. High performance in this case is measured in terms of the confinement enhancement achieved over the L

Spectral observations of ions of beryllium in the JET plasma are described and are interpreted in terms of the interplay of atomic reactions and local plasma conditions. The methods of generalized-collisional-radiative theory are extended and used to

We have carried out quantal calculations for the dielectronic recombination of C 3+ in an electric field. We have used these results in a collisional-radiative model for a carbon seeded hydrogen plasma. We find that the plasma microfield increases th
