The invention relates to the field of accelerator technology and can be used as an injector to create horizontal and vertical low-speed streams of charged particles in a test vacuum chamber.

Known injector of charged dust particles, consisting of a hopper chamber formed the stimulating electrode and the inner side of the charging electrode, the charging chamber formed by the outer side of the charging electrode and the housing, the needle (Akishin A. I., Novikov L. S. equipment and Technique of simulation testing of materials of spacecraft. - M.: Izd-vo Mosk. University press, 1990, 90 p.).

The closest analogue is the injector of charged dust particles consisting of a body, a charging electrode, the charging chamber, the outer composite electrode of the charging chamber, the needle (or needles), bunker electrode, hopper camera and microplates (N. D. Semkin, A. V. Pekov, K. E. Voronov, S. M. Shepelev, N. L. Epiphany. The injector of charged dust particles //Instruments and experimental techniques, No. 3, 2006. Page: 154-159).

However, it has several drawbacks: a small stream of particles at the output, can create a thread in only one horizontal plane.

The task: to develop an injector of charged dust particles with increased yield of charged dust particles and two su�the tion of movement of the stream of charged dust particles - the vertical and horizontal.

The task is achieved in that in the injector of charged dust particles, comprising a housing, charger, battery, camera, external composite electrode of the charging chamber, hopper electrode, hopper chamber and microsocial, according to the invention, the charging electrode has an elliptical shape that has two set of carbon filaments directed in horizontal and in vertical directions, the outer composite electrode comprises two output ports directed in a horizontal and vertical plane at the outlet of the injector is equipped with metal mesh.

The invention is illustrated by drawings, where Fig.1 shows the main view of the injector and Fig.2 shows a longitudinal section of the injector.

The device includes a housing 1 in which is located the charging chamber 2, formed by a charging electrode 3 and the outer composite electrode of the charging chamber 4, in which the 5 horizontal and 6 vertical holes, in the holes of the metal mesh 7, 8 horizontal and 9 vertical set of carbon filaments that are installed on the charging electrode 3 coaxial and 5 horizontal and 6 vertical outlet hole of the injector, respectively, hopper chamber 10 is connected to the charging chamber 2 through the connecting sleeve 11, in b�nkernel the camera 10 is installed bunker electrode 12 and the piezoelectric radiator 13, in bunker chamber 10 filled micropowder 14.

The device operates as follows: when the high voltage supply bunker electrode 12 and the alternating voltage of the resonant frequency of the piezo oscillator 13 micron particles 14 are set in motion under the action of electric field and mechanical vibrations of the piezo oscillator, as a result of random motion of particles in the hopper chamber 10 through the connecting sleeve 11 is the release of particles into the cavity of the charging chamber 2, in the charging chamber, the particles of the micropowder continue their chaotic motion until you can touch the tip of the needle 8 horizontal or vertical 9 set of carbon filaments upon contact of the particles with the tip of the needle she reported the charge, and under the influence of an electric field the particle leaves the charging chamber 2 through 5 horizontal or vertical 6 holes have a metal grid 7, the elliptical shape of the charging electrode provides the highest probability of the particle motion along two paths - horizontal and vertical.

Thus, increasing the flow of charged particles at the exit of the injector and is supplied charged dust particles simultaneously in two directions - horizontal and vertical.
