During a tokamak discharge, several control modes may have to be run in sequence in order to perform the control of the different discharge phases. The transitions between these control modes are not always easy to handle because in most cases the coupling between the controlled plasma quantities is not taken into account in each control mode design process. This paper presents a new Multi-Inputs/Multi-Outputs...
Magnetic fusion research worldwide is now, with ITER, about to demonstrate the scientific feasibility of fusion energy production. Feedback control of fusion experiment gets more and more crucial both for performance, stability and machine protection. The Tore Supra tokamak is well suited to tackle these issues due to its unique capability to perform long duration discharges with many actuators/sensors...
The Tore Supra tokamak is well adapted to sustain long duration non-inductive discharges using the lower hybrid (LH) heating and current drive as the main power source. In these conditions the LH power deposition profile is strongly linked to the current density profile and can be deducted from the hard X-rays (HXRs) measurements which are produced by the suprathermal electrons (SE) generated by the...
