摘要
A simple one-dimensional numerical model including generation, acceleration and loss effects for runaway electrons are used to deduce the runaway energy εr. The simulation results are presented in a form of a scaling law of εr on plasma parameters. The scaling of εr and therefore the runaway confinement time εr and runaway electron diffusivity Dr have been studied in HL-1M tokamak, by measuring the hard-X ray spectra under different experimental conditions. A tentative explanation for the scaling of obtained data based on the effects from magnetic turbulence is presented.
