摘要： An RF hollow cathode plasma source consists of a vacuum chamber, a pipe, a hollow cathode, at least two compartments, a conduit and input electrodes. The pipe is inserted into the chamber for introducing working gas into the chamber. The hollow cathode is disposed in the chamber and formed with a large number of apertures. At least two compartments are located below the hollow cathode. Each of the compartments includes small apertures for uniformly spreading the working gas into the apertures of the hollow cathode. The conduit is disposed along two sides of the hollow cathode to circulate cooling water around the hollow cathode. The plural input power leads are arranged near the hollow cathode. The input power leads, the pipe and the conduits are connected to the hollow cathode though the electrically-insulated walls of the grounded vacuum chamber.

摘要： A hollow-cathode plasma generator includes a plurality of hollow cathodes joined together and connected to a power supply for generating plasma in vacuum. Each of the hollow cathodes includes at least one fillister defined therein, a fin formed on a side of the fillister, an air-circulating tunnel in communication with the fillister and a coolant-circulating tunnel defined therein. The fillister is used to contain working gas. The fin receives negative voltage from the power supply for ionizing the working gas to generate the plasma and spread the plasma in a single direction. The working gas travels into the fillister from the air-circulating tunnel. The coolant-circulating tunnel is used to circulate coolant for cooling the hollow cathode.
