Abstract

During the 1987 run, TFTR reached record values of Q_DD, neutron source strength, and T_i(0). Good confinement together with intense auxiliary heating has resulted in a plasma pressure greater than 3*10 ⁵ Pascals on axis, which is at the ballooning stability boundary. At the same time improved diagnostics, especially ion temperature profile measurements, have led to increased understanding of tokamak confinement physics. Ion temperature profiles are much more peaked than previously thought, implying that ion thermal diffusivity, even in high ion temperature supershot plasmas, is greater than electron thermal diffusivity. Based on studies of the effect of beam orientation on plasma performance, one of the four neutral beamlines has been re-oriented from injecting co-parallel to counter parallel, which will increase the available balanced neutral injection power from 14 MW to 27 MW. With this increase in balanced beam power, and the addition of 7 MW of ICRF power it is planned to increase the present equivalant Q_DT of 0.25 to close to break-even conditions in the coming run.
