Effect of plasma on the radio-technical characteristics of the Uragan-2M torsatron matching RF systems
There were carried out qualitative studies of the effect of plasma parameters during the RF disharge wall conditioning in a helium atmosphere on the quality factor of the antenna oscillating circuit at Uragan-2M torsatron. The quality factor is determined from the ratio of the electric current in th...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | There were carried out qualitative studies of the effect of plasma parameters during the RF disharge wall conditioning in a helium atmosphere on the quality factor of the antenna oscillating circuit at Uragan-2M torsatron. The quality factor is determined from the ratio of the electric current in the circuit to the feed current. The dependence of the quality factor of the toroidal steady magnetic field as well as on the helical field is analyzed. The dependence on the helical field is much stronger; with its increase the quality factor increases that is accompanied with reduction of the antenna load. Also, the ratio of idling current in the antenna (when the plasma even less) to the current in the antenna is measured during the discharge. The dependence of this parameter on the toroidal magnetic field and the neutral gas pressure is studied. |
