Abstract

Izgudrojums attiecas uz elektroniku, konkrēti - uz tehnoloģiska pielietojuma gāzizlādes elektronu lielgabaliem, un var tikt izmantots kausēšanai, iztvaicēšanai un citiem termiskiem procesiem, ko veic vakuumā, izmantojot dažādas gāzes, ieskaitot reaktīvās gāzes, un jaudīgus elektronu kūļus. Tā mērķis ir darba spiedienu diapazona paplašināšana, termiskajos procesos izmantojot gāzizlādes elektronu lielgabalus un palielinot to darba stabilitāti. Piedāvātais gāizlādes elektronu lielgabals, kas satur hermētiskā korpusā uz augstsprieguma izolatoriem izvietotus katodu un anodu, kura ass sakrīt ar katoda asi un kurā ir atvērums elektronu staru izvadei, kā arī satur pie anoda pievienotu staru vadu ar divām fokusējošām lēcām un kūli novirzošām spolēm, kuras ir piestiprinātas pie staruvada, ir raksturīgs ar to, ka starp fokusējošo lēcu un novirzošajām spolēm ir izvietota gāzes balasta kamera, kura aptver staruvadu, ir aprīkota ar atsūknēšanai paredzēto īscauruli un ar staruvadu ir savienota ar atvērumiem, kuru šķērsizmērs nepārsniedz 5 līdz 6 mm, bet to summārā gāzes vadītspēja pārsniedz staruvada vadītspēju starp gāzes balasta kameru un tā griezumu.The invention relates to electronics, concrete & emacration-to-technology & gateway & gateway & emacration electron guns, and can be used for ē š evacuation ē š and other thermal processes performed by ā ā g ā s, including Reaction ī v Ā s Ā s Ā g ā gus electron ū ļ us.
