Long slide-away discharges in the COMPASS tokamak
Other conference contribution, 2016
In this contribution, long runaway electron (RE)
dominated discharges achieved in the COMPASS tokamak are presented. The extensive
length is possible due to a low consumption of available volt-seconds of the
tokamak transformer in this type of discharge. Energetic electron losses in this
regime seems to be modulated mainly by small oscillations of a radial position (controller
setting) unlike in the RE discharges at higher electron density, where various
MHD phenomena affect the evolution of the losses. The behaviour of the slide-away
plasma is studied using magnetic coils, HXR detectors, ECE system and a pair of
3He proportional counters of neutrons. The plasma scenario is also modelled using
Fokker-Planck codes.
