Wall-stabilized arcs are commonly used as excitation sources of atoms and low charged ions. Distributions of plasma parameters in the gap between two subsequent stabilizing plates were studied in argon and helium which are commonly used as 'working gas' in experiments aimed at determination of atomic constants. The results were obtained solving set of equations describing plasma in local thermal equilibrium (LTE). As conditions of LTE may be not completely fulfilled obtained absolute values obtained by this method could be deviated from the real one. Nevertheless, the shape of spatial plasma parameters distributions ought to properly represent shape of the plasma. Obtained results reveal very small gradients of plasma parameters in the central part of this gap. This result can be important in future planning of experiments with side-on plasma observation.
