This novel type of generator is based on a fast mixing of hybrid argon plasma jet of DC electric arc and RF discharge with a neutral molecular oxygen stream. Arc plasma jets have a much higher density of electrons than RF plasma jets to compensate the electro-negativity of oxygen and they can be operated at a higher pressure for an efficient supersonic expansion cooling in DOIL. An RF discharge is applied to the DC arc plasma jet at the hollow anode of the plasmatron to switch it from a hot-spot mode to a diffusive mode.
