JT60-SA Research objectives and Strategy• Reliable Tokamak operation at high N
– “explorations in ITER- and DEMO-relevant plasma regimes in terms of the non-dimensional parameters (such as the normalized poloidal gyro radius *, the normalized collisionality * and the normalized plasma pressure N)”
• Long Pulse/Steady state operation– “demonstrates the real-time control in long pulse discharges exceeding
the longest time scale governing the plasma system”
