THE HYBRID OSD V1 Unified Framework for Plasma Control and Disruption Avoidance in Accelerating Tokamak Regimes

Abstract Tokamak plasmas in ramp-up, high-β, and hybrid regimes are subject to rapid parameter acceleration (α > 0), dense MHD coupling, diagnostic noise, control delays, and synergistic external stressors. Conventional quasi-static criteria (β_N, Greenwald density, q_95, ideal MHD limits) often fail to anticipate rate-induced disruptions with adequate lead time. THE HYBRID OSD V1 integrates the author’s prior works — Ψ-theory, Geometry of Instability, Temporal Stability, TFT, OSD v1.2, A-11 module — into a single, logically consistent multi-level framework for disruption prediction and mitigation.
