A sparse-grid probabilistic scheme for approximation of the runaway probability of electrons in fusion tokamak simulation
Minglei Yang, Guannan Zhang, Diego del-Castillo-Negrete +2
Runaway electrons (RE) generated during magnetic disruptions present a major threat to the safe operation of plasma nuclear fusion reactors. A critical aspect of understanding RE d…
