A single frame antenna is used for plasma production below the cyclotron frequency at the medium-size Uragan-2M torsatron which has started operation at the end of year 2006. Its sizes and the regime of plasma production are chosen using the numerical modeling. In the numerical analysis, time-harmonic Maxwell's equations are solved and the power deposition to the electrons is calculated. In the calculations the plasma density is varied in the range n{sub p}{approx}10{sup 8}-10{sup 13} cm{sup -3}. The single frame antenna provides the core power deposition at the low densities. With increase of the plasma density the power deposition per particle decreases and the power deposition profile worsens since more power is delivered to the plasma periphery. The first experimental results on plasma production in the Uragan-2M torsatron are presented and discussed.
