Multi-component alloys are emerging as promising metallic materials for cryogenic applications for their excellent combination of high ultimate tensile strength and good ductility. But their low yield strength can severely limit their applications. Lattice distortion is emerging as a feasible method in overcoming this dilemma. Here, we investigate …

Disruption prediction and avoidance is a critical need for next-step tokamaks such as ITER. The Disruption Event Characterization and Forecasting Code (DECAF) is used to fully automate analysis of tokamak data to determine chains of events that lead to disruptions and to forecast their evolution allowing sufficient time for mitigation or full av…

A theoretical model for investigating the effect of the trapped energetic particles EPs on the resistive wall mode RWM instability is proposed. The results demonstrate that the trapped EPs have a dramatic stabilizing effect on the RWM because of resonant interaction between the mode and the magnetic precession drift motion of the trapped EPs. The r…
