METHOD OF PRODUCING ELEMENTS AND ASSEMBLIES OF ION OPTICAL SYSTEM (VERSIONS), ION-OPTICAL SYSTEM Russian patent published in 2017 - IPC H01J3/38 H01J9/02 

FIELD: physics.

SUBSTANCE: invention relates to plasma engineering, namely to ion systems, and can be used in aerospace engineering, in development, manufacturing and assembling of ion optical system (IOS) of ion engines (IE). In method of making and assembling of ion optical system, based on provision of axisymmetric holes in electrodes and gap between electrodes according to the invention: making of holes is carried out from base, representing at least two basic holes made in each electrode; base if formed of at least two non-uniformly located holes; processing of holes in electrodes is made by machine with digitally program control; processing of holes in electrodes is made by machine with digitally program control by the same program; holes in electrodes are made with help of spark erosion processing; after making holes in electrodes their electrical polishing is made; alignment of holes between electrodes is provided by adjustment of alignment of basic holes; adjusting clearance is provided by reworking or selection of shim washers, wherein electrodes are thrusted against at least three elements, representing combination of ceramic insulators and adjusting washers.

EFFECT: simplified provision of alignment between holes in electrodes during assembling of IOS; adjustment of gap between electrodes during assembling of IOS.
