Chang Liu, 刘畅, is a postdoctoral research associate at the Theory Department of the Princeton Plasma Physics Laboratory. He received his PhD in 2017 from Princeton University, studying the physics of runaway electrons in tokamaks, advised by Dr. Dylan Brennan and Prof. Amitava Bhattacharjee.
His work focuses on the the kinetic physics of high energy runaway electrons generated in tokamak discharges. Specifically, he studied the excitations of various plasma waves due to runaway electrons, and how these waves can affect the runaway electrons dynamics. His theory calculations and numerical simulation results show these wave-particle interaction can have significant effect on the runaway electron avalanche rate. Many of the new findings have been confirmed in recent tokamak experiments.
