The power balance of a magnetically confined surface-wave-sustained argon plasma is derived from the results of a fully self-consistent one-dimensional hydrodynamic model (COSMOS-1). The influence of the operating parameters on the maintenance electric field and the power balance of the discharge is examined. Both for magnetized and for unmagnetized discharges, the power balance is shown to depend weakly on the spatial distribution of the power deposition within the plasma, and is thus similar for any HF plasma under identical experimental conditions. For magnetized discharges, results show that the power balance is independent of the wave frequency and is only controlled by the magnetic field intensity.
