Long slide-away discharges in the COMPASS tokamak
Konferensbidrag (offentliggjort, men ej förlagsutgivet), 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.
