Plasma effective charge in OH-discharges at the L-2M stellarator after a vacuum chamber boronization
The paper presents results of experiments carried out at the L-2M stellarator after boronization of the vacuum chamber. Changes in the impurity content of plasma were detected by optical methods and it was necessity to recalculate the effective charge. From the electric conductivity of OH-plasma, the effective charges values were calculated for various electron concentrations. Data on plasma effective charge versus electron concentration was presented. A conclusion on effect of boronization on the effective charge of plasma was drawn.
