Integrated Scenario in JET Using Real Time Profile Control

The recent development of real time measurements and control tools in JET has enhanced the reliability and reproducibility of the relevant ITER scenarios. Diagnostics such as charge exchange, interfero-polarimetry, Electron Cyclotron Emission (ECE) have been upgraded for real time measurements. In addition, real time processes like magnetic equilibrium and q profile reconstruction have been developed and applied successfully in real time q profile control experiments using model based control techniques. Plasma operation and control against MHD instabilities are also benefiting from these new systems. The experience gained at JET in the field of real time measurement and control experiments operation constitutes a very useful basis for the future operation of ITER scenarios.
