Modeling of the high-frequency electrodeless discharge (HFED) in argon-mercury mixture has been performed. A stationary collision-radiative model for argon-mercury plasma has been developed. A method of the self-consistent solution for the plasma-field system has been proposed. Discharge properties were investigated in the numerical simulation. The electron density, electron temperature and absorbed electromagnetic field power versus cold spot temperature and argon pressure were calculated. The intensities of mercury spectral lines X = 404.66 nm, A. = 435.83nm and X = 546.07 nm were measured at a wide range of the of argon filling pressure, cold spot temperature and the coil current variations. Based on the developed model, the radiation characteristics of the discharge plasma were calculated, being in good agreement with the experimental data.
