SOURCE OF IONISATION BASED ON BARRIER DISCHARGE Russian patent published in 2013 - IPC H01J49/00 

FIELD: electricity.

SUBSTANCE: in a device for generation of ions, comprising an ionising chamber, including the first electrode, the second electrode arranged opposite to it, and a dielectric element installed between the first and second electrodes and tightly adjacent to the working surface of the first electrode, and also a source of high voltage, according to a utility model, the second electrode is arranged in the form of a metal cap, covering the dielectric element with the first electrode installed on it, besides, the bottom of the second electrode is arranged in the form of a grid, covered with a thin dielectric layer coated at both sides, the area of the working surface of the first electrode is commensurate to the maximum to the area of the grid of the second electrode, and the dielectric element is arranged in the form of the cap and is installed inside the second electrode.

EFFECT: higher efficiency of device operation, its increased service life due to increased service life of discharge electrodes, and higher stability of working characteristics of a device.
