Abstract:
1. An ionization device for ionization of particles in the form of a flow in a direction of propagation of said particles comprising: a sealed vacuum chamber in which said ionization device is located; at least one hollow cylindrical body having a central longitudinal axis and a longitudinal slit having a length, said flow of said particles coinciding with said central longitudinal axis; a source of electrons located outside said at least one hollow cylindrical body to form an electron beam directed onto said flow of particles through said longitudinal slit in the direction perpendicular to said direction of propagation; means for application of a positive voltage to said at least one hollow cylindrical body to form an anode slit for said electron beam; and a zone of ionization of said particles that has a length and is arranged on said longitudinal axis.
