Plasma Edge Physics

The thin, complex boundary region that disproportionately sets overall performance.

Why it matters

Sets core performance & exhaust

The plasma edge — the pedestal and scrape-off layer — punches above its weight: the pedestal height strongly sets core performance (through profile stiffness), and the scrape-off layer governs exhaust. Edge physics is where confinement, stability and exhaust all meet.

HYPERION's negative triangularity is an edge-physics choice aimed at benign ELM behaviour.
