WIDE-APERTURE ION-OPTICAL SYSTEM OF GASEOUS-DISCHARGE SOURCE OF IONS Russian patent published in 1995 - IPC

Abstract SU 1790314 A1

FIELD: ohysics. SUBSTANCE: invention refers to gaseous-discharge sources of ions. accelerating electrode 2 is manufactured in the form of grids 3 and 4. Ions fromplasma emitter 1 pass through grids and hit collector 5 of ions. Secondary electrons are reflected from collector by grid 4. Current of secondary electrons from grids 3 and 4 is small because of high transparency of grids. EFFECT: increased density of ion current and homogeneity of ion beam. 1 dwg
