An active gas generator that generates active gas by activating supplied material gas through discharge in a discharge space formed between a high-voltage side electrode component and a ground side electrode component of an active gas generation electrode group. A combined structure of covers completely separates the discharge space from an alternating-current voltage application space, and includes, independently from the alternating-current voltage application space, a material gas flow path for a material gas supply path, through which externally supplied material gas is guided to the discharge space. A housing contact space formed between a metal housing and each of the covers and an electrode component installation table is completely separated from the alternating-current voltage application space and the discharge space.

A method for generating atmospheric pressure cold plasma inside a hand-held unit discharges cold plasma with simultaneously different rf wavelengths and their harmonics. The unit includes an rf tuning network that is powered by a low-voltage power supply connected to a series of high-voltage coils and capacitors. The rf energy signal is transferred to a primary containment chamber and dispersed through an electrode plate network of various sizes and thicknesses to create multiple frequencies. Helium gas is introduced into the first primary containment chamber, where electron separation is initiated. The energized gas flows into a secondary magnetic compression chamber, where a balanced frequency network grid with capacitance creates the final electron separation, which is inverted magnetically and exits through an orifice with a nozzle. The cold plasma thus generated has been shown to be capable of accelerating a healing process in flesh wounds on animal laboratory specimens.

A system for generating and delivering a low temperature, wide, partially ionized tunable plasma stream is described. The system employs a fast rising, repetitive high voltage pulse generator, flowing gas, and a plasma head to produce the described atmospheric pressure plasma stream and its associated active species. The plasma head may have an exit slit with a relatively wide dimension to produce a relative wide plasma stream. Electrodes may be located proximate the exit slit, for example one in an interior of the plasma head via with gas flows toward the exit slit, and the other exterior to the plasma head and offset from the exit slit. The plasma may include baffle material to enhance a uniformity of flow through and across the exit slit. Plasma heads with having exit slit with different widths may be provided as a kit.
