CGC Urukurikirane rwa Cryogenic Superconducting Magnetic Itandukanya

Uru ruhererekane rwibicuruzwa bifite urwego rukomeye rwa magnetiki rukuruzi idashobora kugerwaho nibikoresho bisanzwe bya electroniki ya magnetiki, kandi irashobora gutandukanya neza ibintu bya magnetiki bidakomeye mumabuye y'agaciro meza.Birakwiriye kugenerwa meteri zidasanzwe, zidafite ferrous ubutare hamwe n’amabuye y'agaciro adafite ibyuma, nko gutunganya ubutare bwa cobalt, kuvanaho umwanda no kweza kaolin na feldspar ubutare butari ubutare, kandi birashobora no gukoreshwa mu gutunganya imyanda no gutunganya amazi yo mu nyanja n’indi mirima.

Ihame ry'akazi

Imashini itandukanya imiyoboro ya magnetiki ikoresha ibiranga ko kurwanya igiceri kirenze urugero ari zeru ku bushyuhe buke, Koresha umuyoboro munini kugira ngo unyure mu gihimba cyinshi cyinjijwe muri helium y’amazi, kandi ushimishwe n’amashanyarazi ya DC yo hanze, kugirango magnetiki arenze urugero itandukanyirizo irashobora kugera kumurongo wa mag- netic imbaraga zumurima hejuru ya 5T, Ubuso bwumurongo wa magnetiki utwara ibyuma bitagira umuyonga Matrix mubyumba byo gutandukanya ibyara ingufu nini-nini ya rukuruzi ya magneti, ishobora kugera kuri 10T, ishobora gutandukanya ibintu bya magneti kandi nayo nuburyo buhebuje murwego rwo gutandukanya magnetiki.

Uburyo bwo gutondekanya bugizwe na silinderi eshatu ziboneka hamwe na silindiri ebyiri. Gutondekanya silinderi hamwe na silindiri isanzwe irashobora kugera kuburinganire bwa magneti, kuburyo uburyo bwo gutondeka bushobora kwimuka mumurima wa magneti munsi yibikorwa byimbaraga nto zo hanze.

Uburyo bwo gutondeka butwarwa na moteri hamwe na sisitemu yo gutwara umukandara kugirango isubirane mugihe cyagenwe. Inzira yo gutandukana nuko silinderi imwe yo gutandukanya itondagura pulp muri magneti hamwe nimbaraga zinyuma zumurima hejuru ya 5T, naho ubundi silinderi yo gutandukana isukurwa hanze ya magneti. Kubera ko nta murima wa rukuruzi uhari, ibice byamabuye y'agaciro ntibibasiwe ningufu za rukuruzi, kandi ubwoya bwicyuma bwogejwe namazi yumuvuduko mwinshi, ibintu bya magnetiki byanditswemo bisohoka hamwe namazi, silinderi itondekanya ikora muri magneti yimuwe ivuye muri rukuruzi, hanyuma itunganywa rya silinderi isukuye isubira kuri magneti kugirango itondekane impyisi, kandi uruziga rusubirwamo, burigihe hariho itondekanya rya silinderi muri magneti kugirango ritondere ifumbire, itezimbere cyane umusaruro.

Ibiranga tekinike

Imbaraga zo hejuru cyane za magnetiki yumurima, coil ikozwe mubintu bya Nb-Ti superconducting ifite imbaraga za magneti zumurenge zirenga 5T, mugihe imbaraga zumurima wa rukuruzi zisanzwe zisanzwe ziri munsi ya 2T, zikubye inshuro 2-5 ugereranije nibicuruzwa gakondo.

Imbaraga zikomeye za magnetique, munsi yumurima winyuma hejuru ya 5T, hejuru ya matrike yemewe na magnetiki mucyumba cyo gutandukanya ibyara imbaraga nini cyane, ishobora gutandukanya neza imyanda ya magneti idakomeye, ikazamura cyane ubwiza bwamabuye y'agaciro atari ubutare. , kandi yujuje ibisabwa byibicuruzwa byo mu rwego rwo hejuru.

Ihindagurika rya zeru ya helium, firigo ya 1.5W / 4.2K irashobora gukomeza gukonjesha, kugirango helium yamazi idahindagurika hanze ya magneti, byemeza ko umubare wamazi wa helium udahinduka, kandi nta mpamvu yo kuzuza amazi ya helium. mugihe cyimyaka 3, kugabanya amafaranga yo kubungabunga.

Gukoresha ingufu nke, ukoresheje tekinoroji yo hejuru yubushyuhe bwo hejuru, kurwanya coil ni zeru nyuma yo kugera kuri superconducting. Firigo ikeneye gusa gukomeza ubushyuhe buke bwa magneti ikora, ikiza amashanyarazi arenga 90% ugereranije na magneti asanzwe.

Igihe gito cyo kwishima. Ntabwo ari munsi yisaha 1.

Amashanyarazi abiri atondekanya kandi akakaraba, kandi arashobora gukora ubudahwema nta demagnetisation, bizamura umusaruro. Ubwoko bwa 5.5T / 300 butandukanya magnetiki itandukanya irashobora gutunganya kaolin kugeza kuri toni 100 / kumunsi yubutare bwumye, kandi 5T / 500 yo gutandukanya magnetiki itandukanya irashobora gutunganya toni 300 / kumunsi ya kaolin.

Inzira yose igenzurwa na microcomputer, kandi ibipimo birashobora gukusanywa mugihe nyacyo, ni ben-

eficial kugenzura umusaruro no kugenzura ubuziranenge.

Ibikoresho bikora neza, ikiguzi cyo kubungabunga ni gito cyane, magnet afite ubuzima burebure bwa serivisi, uburemere bworoshye

no kwishyiriraho byoroshye.
