Abstract
The conditions leading to the development of fast-scale ( f ~ 0.2–1.5 MHz) electromagnetic oscillations in the periphery regions of plasma at an early stage of disruption in the T-10 tokamak are analyzed. Spatial and temporal characteristics of fast-scale oscillations are investigated by moving magnetic and electric probes mounted inside the tokamak vacuum chamber. Analysis reveals that initiation of the fast-scale oscillations can be related to the development of arc discharges in plasma near the T-10 tokamak limiters. The transition to a major disruption and collapse of the plasma current is accompanied by a sharp increase in the amplitude of the fast-scale electromagnetic oscillations. Monitoring the fast-scale electromagnetic oscillations at the plasma periphery can be an important trigger for systems to safely quench the discharge in a to-kamak.中文翻译:
