摘要： The present invention relates generally to apparatus and methods used in chemically reducing pollutants in effluent gas flow. More particularly, the present invention relates to ionization of effluent gas from an effluent gas source by passage of the effluent gas through a resonance field, and potentialization and purification of the effluent gas by passage of the effluent gas through a continuous electrical arc. Preferably, the resonance field and the continuous electrical arc are both generated by an alternating current. The result of using the apparatus and method of the present invention is a release of stabilized air particles without a high consumption of energy, and without producing waste products requiring subsequent collection.

摘要： Annular arrangements of thermionic filaments adjacent opposite axial ends a chamber within which argon gas at low presure is confined, generate steady state plasma with uniformity by low energy emission of gas ionizing electrons from the filaments. The ionizing electrons and plasma generated are axially confined between grids at the axial ends of the chamber and radially confined by a low intensity magnetic field generated by an external magnetic coil.

摘要： Apparatus wherein a partially ionized mass of gas is enclosed by a rotationally symmetric, axially elongate housing and set in rotation by a force which arises as a result of a substantially axial magnetic field constant in time and an electric current having a non-zero vector component in the radial direction, whereby positively charged ions originating from a centralized axial gas discharge arc region and moving at a high speed of rotation set the whole mass of gas in rotation by pulse transfer, said housing being lined on the inside with annular wall electrodes segmented in non-azimuthal direction and arranged against each other; the inside wall of said housing at an extremity thereof curving toward the center axis and approaching a centrally mounted electrode of opposite polarity, the wall electrodes being connected with variable resistors which are adjusted so that the voltage applied to the wall electrodes increases blockwise from a minimum value at a chosen point on the axis of the housing to the grid-or anode voltage of the said axial gas discharge arc region, whereby the wall electrode which is closest to the central electrode exhibits with respect thereto the smallest potential difference of all the wall electrodes, in an extreme case the potential difference being zero.

摘要： In the disclosed electron gun positive ions generated by a hollow cathode plasma discharge in a first chamber are accelerated through control and shield grids into a second chamber containing a high voltage cold cathode. These positive ions bombard a surface of the cathode causing the cathode to emit secondary electrons which form an electron beam having a distribution adjacent to the cathode emissive surface substantially the same as the distribution of the ion beam impinging upon the cathode. After passing through the grids and the plasma discharge chamber, the electron beam exits from the electron gun via a foil window. Control of the generated electron beam is achieved by applying a relatively low control voltage between the control grid and the electron gun housing (which resides at ground potential) to control the density of the positive ions bombarding the cathode.

摘要： A plasma-generation system is provided that includes a variable-frequency microwave generator configured to generate microwave power and a plasma applicator configured to use the microwave power from the microwave generator to (i) ignite a process gas therein for initiating a plasma in a plasma ignition process and (ii) maintain the plasma in a steady state process. The system also includes a coarse tuner connected between the microwave generator and the plasma applicator. At least one physical parameter of the coarse tuner is adapted to be set to achieve coarse impedance matching between the microwave generator and the plasma generated during both the plasma ignition process and the steady state process. A load impedance of the plasma generated during the plasma ignition process and the steady state process is adapted to vary. The microwave generator is configured to tune an operating frequency at the set physical parameter of the coarse tuner.

摘要： Methods of synthesizing nanoparticles of an isotope using a laser beam are described herein. The methods include generating the laser beam, directing the laser beam to the target to convert the target into a plasma state, and bombarding the target in the plasma state with the laser beam to maintain the target in the plasma state and synthesize the nanoparticles of the isotope. During bombarding the target in the plasma state with the laser beam, the laser beam is configured to have a pulse frequency and peak laser intensity that accelerates electrons in the plasma state and maintains the plasma state at a temperature high enough to provide for the synthesis of the nanoparticles of the isotope. Apparatuses for synthesizing nanoparticles of an isotope using a laser beam are also described herein.

摘要： The plasma sensor monitors parameters characterizing the condition of the plasma during the treatment phase and/or the change thereof in order to recognize a prefiguring or already occurred interruption of the plasma in this manner and to avoid this interruption and, in the ideal case, avoid this by already changing the voltage form previously. The mentioned mechanisms can be used by the control device (22) also during a pulse packet. The length of each pulse packet is adapted at each change of the voltage form according to their characteristics in order to guarantee a constant average power.
