Development of new fuelling method

- Compact Toroid (CT) Injection ー

Fuelling method required for fusion reactor :

  • Efficient fuelling into plasma core
    Right arrow Realization of high density exceeding the density limit

 

JT-2M, CT injector

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

CT injected into the JFT-2M vacuum vessel
