Towardscontrol ofsteady state plasmaonToreSupra

Magnetic Fusion Research worldwide isnow,with ITER,abouttodemonstrate thescientific feasibility offusion energy production. Feedback control offusion experiment gets moreandmorecrucial bothforperformance, stability and machine protection. TheToreSupratokamakiswellsuited to tackle these issues duetoitsunique capability toperform long duration discharges withmanyactuators/sensors available. The ToreSuprarealtimemeasurements andcontrol systemhas beenupgraded toaddress schemesdedicated tolongpulse operation withsimultaneous control ofanincreasing number ofplasmaparameters. A review ofrecent progress onseveral keycontrol issues likemeasurement drift during longpulses, highefficient fuelling, plasmacurrent profile tailoring, plasma facing componentprotection andselfplasmaprotection is given.
