    摘要： A plasma generator comprises a metallic tube of small diameter inside which can circulate a gas such as argon at a small flow rate, which is discharged at the front end of the tube. The tube is coupled with an energizing structure which can comprise a frequency generator supplying electromagnetic microwave via a coaxial connection, a coupling structure allowing the transfer of the energy of the generator to the front portion of the metallic tube. In the absence of a gas current in the tube, the front portion radiates the energy transmitted to it in the manner of an antenna. When a gas is discharged at the end of the tube, said energy allows maintaining a plasma in front of the latter.This plasma generator device is usable in many applications, such as a blowtorch a light source or torch usable in spectrography, a plasma motor or an ion source.

    摘要： In an improved plasma torch, a metal tube delivers a plasma-generating gas to an end discharge outlet. The delivery tube is excited by microwave energy by means of a waveguide of rectangular cross-section. The tube traverses the waveguide through openings of larger diameter than the delivery tube. Metal sleeves are advantageously provided around the tube on each side of the waveguide. Two gases can be delivered to the plasma within concentric tubes. The plasma-formation zone can be moved further away from the waveguide by providing lateral impedance-matching devices along the sleeve.

    摘要： A device which generates plasma by energizing a column of gas with a high frequency periodic electric field of a frequency of at least 100MHz. The generating means extends over only a part of the gas column and the power of the energizing field is such that the plasma generated includes and extends beyond said part of the gas column. In one embodiment the gas column is contained in an elongated insulating casing and the generating means comprises a first metallic tube open at both ends and surrounding a part of the casing, a second tube enclosing the first, and a connecting ring between the first and second tubes.

    摘要： The invention relates to a plasma reactor including a housing which receives a selected gas flow, a microwave generator, and waveguide means to supply the microwaves to the housing according to a non-resonant coupling wherein the housing does not dissipate in the form of electromagnetic radition the ultrahigh frequence energy which is imparted to the housing in the presence of gas. According to a general definition of the invention, the housing being of a large size, the terminal portion of the waveguide means is progressively reduced in one direction and widened in the other direction till it reaches a flat rectangular cross-section surrounding completely the housing, and it forms a non-resonant coupling with the housing.
