ION SOURCE Russian patent published in 1995 - IPC

Abstract SU 1725687 A1

FIELD: instrumentation engineering. SUBSTANCE: ion source has cathode assembly with axial holes, annular anode, electron collector, ion extraction system, power supply, all arranged coaxially and in tandem. Ion source is provided, in addition, with annular anode arranged coaxially in respect to cathode assembly on side opposite to that facing main anode. Anode is connected to additional power supply. Cathode assembly has two disks arranged coaxially and spaced apart, with hole along axis. Grid assembly whose grid planes are inclined through certain angle to source axis is placed between disks. EFFECT: enlarged functional capabilities. 1 dwg
