Negative Triangularity by Design
Shaping the plasma the 'wrong' way to suppress edge instabilities without extra control systems.
- Triangularity
- -0.30
- Benefit
- Passive ELM suppression
HYPERION's negative triangularity (δ = -0.30) is a distinctive stability choice: it can access good confinement while naturally suppressing edge-localised modes, easing the divertor's life without a bolt-on ELM-control system. It reflects a design philosophy of solving problems through configuration rather than added machinery.
Common questions
HYPERION's negative-triangularity shape (δ = -0.30) can suppress edge-localised modes while keeping good confinement — taming the plasma edge without violent bursts, a deliberate stability choice.
Negative triangularity is an active, promising area demonstrated on several tokamaks. Kronos adopts it as a design choice grounded in that experimental work, not as a novel bet.
