Fusion Plasma Research
Development of new fuelling method
- Compact Toroid (CT) Injection -
Fuelling method required for fusion reactor :
  • Efficient fuelling into plasma core
    Realization of high density exceeding the density limit

Injection of donut-shape plasma (CT) accelerated by electromagnetic force to super high velocity

Direct injection into the central region of plasma

CT injected into the JFT-2M vacuum vessel
CT parameters
Velocity (km/s) 300
Density (x1021m-3) 9
