Av. Melnikov et al., SPACE AND TIME EVOLUTION OF PLASMA POTENTIAL IN T-10 UNDER VARIATION OF MAIN GAS INFLUX, IEEE transactions on plasma science, 22(4), 1994, pp. 363-368
The HIBP method was used in the experiments on the T-10 tokamak to mea
sure the space potential distribution as a function of gas feed. A hig
h electric field was observed in the region where the ionization of ne
utrals takes place. The correlation of the potential with the gas flux
dynamics and the MHD activity was also found.
