Yv. Kholnov, Structure of fluctuations in the floating potential and ion saturation current in the edge plasma of the L-2M stellarator, PLAS PHYS R, 27(9), 2001, pp. 794-798
Results are presented from the measurements of the ion saturation Current,
the floating potential, and their fluctuations in the edge plasma of the L-
2M stellarator. Distinguishing features in the distribution of the ion satu
ration current and the floating potential near the separatrix are revealed
and examined, Based on the cross correlation measurements with probes posit
ioned at different toroidal angles, it is concluded that fluctuations in th
e ion saturation current are related to fast vertical displacements of the
plasma column, whereas fluctuations in the floating potential have the form
or waves propagating in the radial direction. (C) 2001 MAIK "Nauka/Interpe
