Abstract:
1. A microplasma source, comprising: a first gas storage unit used for storage of a first gas; a second gas storage unit used for storage of a second gas; a microplasma-generating unit, comprising: a gas transmission chamber having a first inlet and a first outlet, wherein the first inlet is connected to the first gas storage unit and used to import a first gas; a protection and heat dissipation chamber of which a side is connected to an inner wall of the first outlet of the gas transmission chamber; a dielectric inner tube having a second inlet and a second outlet and penetrating through the protection and heat dissipation chamber, wherein the second inlet is communicated to the gas transmission chamber; an electrode arranged outside at the second outlet of the dielectric inner tube, disposed between the second outlet of the dielectric inner tube and a third outlet of a hollow metal tube disposed in the gas transmission chamber and the dielectric inner tube, and located in the protection and heat dissipation chamber; and the hollow metal tube disposed in the gas transmission chamber and the dielectric inner tube, and having a third inlet and said third outlet, wherein the third inlet is used to import a second gas and the third outlet is disposed within the second outlet to form a gas mixing zone; and a power supply unit coupled to the electrode and the hollow metal tube to generate microplasma therebetween, wherein the first gas and the second gas mix in the gas mixing zone between the electrode and the hollow metal tube.
