Wendelstein 7-X
The flagship stellarator demonstrating disruption-free, steady-state confinement.
- Type
- Stellarator
- Demonstrates
- Disruption-free steady state
Wendelstein 7-X is the leading optimised stellarator, demonstrating that carefully shaped external coils can confine plasma steadily without a plasma current or disruptions. It defines the state of the art for the stellarator route.
Kronos does not use a stellarator, but W7-X frames why the tokamak's current — which the breeder must drive — is a design consideration.
Common questions
W7-X is the leading stellarator, demonstrating that intricately shaped coils can confine plasma steadily without a plasma current — and so without disruptions.
It is the main alternative disruption-free route; Kronos achieves disruption-free operation instead through its linear burner, avoiding the stellarator's coil complexity.
