Ibisabwa kugira ngo habeho irangi rya cathode ion

Ibi bikurikira birakenewe kugira ngo ucane urumuri rw'umurambararo wa cathode rudafite aho ruhuriye:

1. Imbunda ifite ubugari bwa cathode ikozwe mu muyoboro wa tantalum ishyirwa ku rukuta rw'icyumba cyo gutwikiramo kandi ishobora gukoreshwa mu gutanga electron zishyushye. Umurambararo w'imbere w'umuyoboro ugororotse ni φ 6 ~ φ 15mm, ufite ubugari bw'urukuta bwa 0.8-2mm.

1. Ingufu zitangwa zigizwe n'amashanyarazi atangira arc hamwe n'amashanyarazi agumana arc mu buryo bungana. Voltage y'amashanyarazi atangwa na arc ni 800-1000V, naho arc ikaza ari 30-50A; Voltage y'arc ni 40-70V, naho arc ikaza ari 80-300A.

Uburyo bwo gusohora arc ya cathode idafite aho ihuriye n'ihinduka riva ku gusohora urumuri rudasanzwe rukajya ku gusohora arc muri "volt ampere characteristic curve". Ubwa mbere, hakenewe ingufu kugira ngo habeho voltage ya 800V yo gutangira kugira ngo habeho gusohora urumuri muri tantalum tube. Ion za argon zifite ubucucike bwinshi ziri muri tantalum tube zirasa kandi zishyushya umuyoboro kugeza ku bushyuhe aho electron zishyushye zisohokera, bigatuma habaho urujya n'uruza rwinshi rwa plasma electron ndetse n'ubwiyongere butunguranye bw'umuyoboro wa cathode idafite aho ihuriye n'ihindagurika ry'umuyoboro. Hanyuma, hakenewe ingufu nyinshi kugira ngo arc decompression ikomeze. Uburyo bwo guhindura kuva ku gusohora urumuri rukajya ku gusohora arc ni bwo bwikora, bityo ni ngombwa gushyiraho ingufu zishobora gusohora voltage nyinshi n'umuyoboro mwinshi.

Niba ibi bisabwa bibiri byibanda ku isoko rimwe ry'amashanyarazi, impera y'ingufu ya kabiri ya transformer igomba gushyirwamo insinga nini cyane mu mpande nyinshi kugira ngo itange voltage nyinshi n'amashanyarazi menshi, bizaba isoko y'amashanyarazi menshi. Nyuma y'imyaka myinshi yo kunozwa, birashoboka guhuza amashanyarazi make yo gutangiza arc hamwe n'amashanyarazi yo kubungabunga arc. Ingufu zo gutangira arc zikoresha insinga nto kugira ngo zizunguruke inshuro nyinshi, zishobora gutanga voltage nyinshi ya 800V kugira ngo zicane imiyoboro ya tantalum kandi zitange urumuri; Ingufu za arc zishobora gutanga volts icumi na amagana ya ampere y'amashanyarazi binyuze mu kuzunguza insinga nini hamwe n'izunguruko nke kugira ngo zigumane umutekano w'ingufu za cathode arc. Bitewe n'isano ry'amashanyarazi abiri kuri tantalum, mu gihe cyo guhindura kuva ku gusohora urumuri kudasanzwe kugera ku gusohora arc, ingufu zombi zizahita zihuza kandi zihinduke kuva kuri voltage nyinshi n'amashanyarazi make kugera kuri voltage nke n'amashanyarazi menshi.

1. Hindura vuba urugero rw'umwuka uvamo umwuka. Urugero rw'umwuka uvamo umwuka uvamo urumuri mu miyoboro ya tantalum ni hafi 100Pa, kandi imiterere ya firime igaragara muri ubwo buryo bworoshye bwo mu mwuka iba ikomeye. Kubwibyo, nyuma yo gutwika umwuka uvamo umwuka, ni ngombwa guhita ugabanya ingano y'umwuka uvamo umwuka kandi vuba uhindure urugero rw'umwuka uvamo umwuka kuri 8×10-1~2Pa kugira ngo ubone imiterere myiza ya firime y'ibanze.

1. Imashini izunguruka ishyirwa ku cyumba cyo gusigamo irangi, aho igikoresho gifatanye n'inkingi ya negative y'amashanyarazi ya bias n'icyumba cyo gufunga gifatanye n'inkingi ya positive. Bitewe n'ubucucike bwinshi bw'umuyoboro wa cathode udafite aho uboshye, voltage ya bias y'igikoresho cyo gusigamo irangi ntabwo ikeneye kugera kuri 1000V, ubusanzwe 50-200V.

5. Shyira coil ya electromagnetic ireba hafi y'igwa rya Gan, maze electromagnetic field ikorwa no gushyira umuriro kuri coil ishobora gushyira electron light hagati mu cyuma, bikongera ubucucike bw'imbaraga z'urujya n'uruza rwa electron.
