Original Abstract
The subject of this paper is the recently developed 2.45 GHz microwave micro torch, which produces a surface wave discharge operating at low power of 25 W. Microwave plasma is generated using surfatron resonator in pure argon and argon with admixtures (up to 1.7%) of nitrogen and oxygen at the gas flow rate of 3 Slm. Two different configurations are used-a standard one and one with an additional metallic plate at the surfatron resonator end limiting the surface wave propagation along the plasma. Plasma parameters like temperatures (rotational, vibrational, electron) along the plasma torch axis as well as distribution of selected active particles are determined. The numeric simulation of the discharge and its properties are included, too. Finally, surface temperature of the fresh pork skin affected by the active particles flow is determined using thermo camera images. The obtained results show applicability of this system for the surface treatment of biological objects and possibility to modify the torch conditions by molecular gases additions.
