Abstract
The runaway electron (RE) beam formation in JA DEMO is simulated using the integrated disruption code INDEX. It is shown that the gamma-ray flux is comparable with that of the published results for ITER and the Compton scattering of gamma rays governs an irreducible minimum of the RE seed (∼ 0:01 - 0:1 A), which can lead to multi-mega-ampere RE beams in the absence of significant radial transport of REs.
Keywords
