Development of new fuelling method
- Compact Toroid (CT) Injection ー
Fuelling method required for fusion reactor :
- Efficient fuelling into plasma core
Realization of high density exceeding the density limit
- Method:
- Injection of donut-shape plasma (CT) accelerated by electromagnetic force to super high velocity
