The study of runaway electron confinement to probe the electromagnetic turbulence in OH, L- and H-discharges of ASDEX

Description

Confinement studies of runaway electrons have been performed in order to elucidate the nature of electromagnetic turbulence and its role in ohmically and beam heated L- and H-plasmas. Under ohmic conditions, the confinement time τR of runaway electrons depends strongly on the choice of qa; in the L-mode, τR degrades with beam power; in the H-phase, runaway electrons are again well confined. With plausible assumptions, a correlation length of the underlying microturbulence of 0.1 cm is found which requires a magnetic perturbation Br/Bo ≅ 10-4 to be consistent with L-mode confinement.
