“…It has to be mentioned that in RFPs the footprint of PWI also shows a poloidal asymmetry between ion and electron drifts, with electron and ion flows separately intercepted by the wall, due to the surface distortion [366,367,577,578]. An example is shown in figure 68.…”

“…The presence of an energetic component in the electron velocity distribution is generally observed in the edge of reversed-field pinch (RFP) experiments. Such observations are based on heat flux measurements [1][2][3][4][5][6][7][8][9], measurements using an electron energy analyser (EEA) [10][11][12][13] or by viewing the x-rays from a target which is inserted into the plasma [14][15][16]. The source of the energetic electrons in the edge region is believed to be associated with stochastic radial transport from the hot central region caused by fluctuations (b r ) of the radial component of the field relative to the equilibrium field [17].…”

“…In particular on the side facing the electron drift direction the thermal load is of the order of 300 MWm -z at r = 12.5 cm [11] and almost an order of magnitude lower on the ion drift side. The high thermal load on the electron drift side can be interpreted, according to the results found in other experiments [5,8,9], as due to a small fraction of energetic electrons travelling from the hotter central region of the plasma to the wall without undergoing collisions [16,18].…”
