N2 - The problem of assessing apparent secondary emission coefficient based on electrical properties of direct-current (DC) glow discharges using numerical modeling is revisited. An analysis of potential sources of uncertainties resulting from errors in experimental data as well as from model assumptions and approximations is presented. An estimation method based on a previously developed analytical model of a DC glow discharge is suggested. Application of the method is demonstrated in the example available in the literature of current-voltage characteristics of DC glow discharges in argon with copper electrodes. Values obtained for the considered data fall into two distinguishable groups, closely corresponding to those for clean and dirty copper cathode surfaces. The obtained preliminary results suggest the feasibility of estimating apparent secondary emission coefficients in DC discharges using numerical modeling.
