METHOD OF CREATING A DIRECTED IONIZING CHANNEL IN AIR Russian patent published in 2019 - IPC H05H1/00 

FIELD: electricity.

SUBSTANCE: invention relates to methods of creating a directed ionizing channel in air and can be used to create devices for scientific research in the field of electricity, in particular for producing gas-discharge plasma in air and analyzing its properties. Device for obtaining a directed ionizing channel in air is electron-beam tube 1 (Fig. 1) and an electrostatic field source, which can be electrostatic machine 2 (Fig. 1). Method of creating a directional ionizing channel in air is carried out as follows. To electron-beam tube 1 (Fig. 1) power supply unit 3 (Fig. 1), which provides operation of electron-beam tube. On the opposite side from the power supply unit to the screen of the cathode-ray tube there connected is metal tube 4 (Fig. 1), which can be made of stainless steel, nickel, aluminum or copper and inside which there is porous material, which, in turn, can be made of ceramic filter 5 (Fig. 1), and before placing ceramic filter into metal tube, filter is impregnated with aqueous solution of heteropolyacid 1–12 of row, having chemical formula H₆[PW₁₀V₂O₄₀], with concentration from 45 to 75 %. After that, the filter is dried for 4–7 hours in a drying cabinet in the temperature range from 30 to 50 °C. Then, filter is inserted into initial part of metal tube 4 (Fig. 1) so that by one side it touches surface of screen of electron-beam tube 1 (Fig. 1). Further, to electrostatic machine 2 (Fig. 1) diluted electrodes insulated high-voltage wires 6 (Fig. 1) with terminals on ends. One terminals are fixed on the balls of the electrodes of the electrostatic machine, and the other terminals are connected on both sides to ceramic filter 5 (Fig. 1) impregnated with heteropolyacid 1–12 of row having formula H₆[PW₁₀V₂O₄₀], after which using the power supply unit includes electron-beam tube 1 (Fig. 1) and waiting for 7 to 15 minutes to ensure stable operation of the electron-beam tube. After stabilization of operation of electron-beam tube smoothly rotate handle of electrostatic machine till appearance of greenish illumination 7 (Fig. 1) at opposite end of metal tube 2 (Fig. 1) and as shown in Fig. 2. With further increase in revolutions of rotating disks of the electrostatic machine, the luminescence becomes more intense owing to ionization of air owing to the directed flow of electrons which occur when the filter is exposed to heteropolyacid and has high-density charges which are formed on the surface of the electron-beam tube and when the ceramic filter is exposed to an electrostatic field. This action leads to reduction of heteropolycomplex, during which excess of charged particles appears on ceramic filter and free electrons are formed, "ejected" from the metal tube on the opposite side from the electron-beam tube, during which a directed ionizing channel in the air is formed.

EFFECT: high stability of the ionizing channel and reduced dependence thereof on weather conditions.
