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.
