FIELD: devices for physical investigations. SUBSTANCE: anode chamber 1 contains working material 2. Spiral-shaped cathode 3 is located in anode chamber. Electrons which are emitted by cathode evaporate working material. Anode chamber provides ionization and excitation of ions. Ion beam is accelerated by electrode 4 and is brought into focus by electrodes 5 and 6. EFFECT: increased ionization rate, increased brightness of ion beam. 1 dwg
