Runaway electrons in an impure plasma

Physics of Fluids, 1976
The electron runaway theories of Kruskal and Bernstein and Lebedev are extended to apply to multiply ionized, multiple species plasmas. The resulting expressions for electron runaway rates are compared with results obtained by Kulsrud, Sun, Winsor, and Fallon from numerical solutions of the Fokker–Planck equation.

Runaway electrons in a tokamak: A free-electron maser

Physical Review E, 1997
In ohmic divertor plasma discharges of the ASDEX upgrade tokamak containing a small population of runaway electrons, fluctuating emission in the microwave region with a very narrow bandwidth is observed. The radiation can be explained by relativistic runaway electrons, which are captured in a ripple resonance of the tokamak and are thus made ...

Runaway electrons in plasma current sheets

Physical Review Letters, 1994
It is shown that a runaway electron population accelerates along the main magnetic field in a Sweet-Parker current sheet. After a characteristic distance the entire current is carried by runaways. The thickness of this runaway sheet is much smaller than the original Ohmic sheet. The influence of microinstabilities is discussed.

Impact of runaway electrons

Fusion Engineering and Design, 1994
Abstract Runaway electrons can cause severe damage to plasma facing components of large tokamaks. The designs proposed for the first wall and divertor of the next large fusion experiment, ITER-CDA (International Thermonuclear Experimental Reactor - Conceptual Design Activities) are investigated.

Hot electrons in one dimension: Electron velocity runaway

Physical Review B, 1987
The solution to the Boltzmann equation for optical-phonon scattering in one dimension, as obtained previously both without and with backscattering, is examined with regard to the question of electron velocity runaway. The results are in accord with previous work on this question, in that forward scattering (\ensuremath{\alpha}=0) leads to runaway above
