Abstract

The simultaneous real-time control of the current and temperature gradient profiles could lead to the steady state sustainment of an internal transport barrier (ITB) and so to a stationary optimized plasma regime. Recent experiments in JET have demonstrated significant progress in achieving such a control: different current and temperature gradient target profiles have been reached and sustained for several seconds using a controller based on a static linear model. The current profile was controlled through the inverse safety factor profile, ?=1/q, and the temperature gradient profile was controlled through the profile of another non-dimensional parameter, rho*Te, which characterizes internal transport barriers in JET (rho*(Te) is the normalized electron temperature gradient introduced in).
