Ni ukubera iki inzitizi ziterwa na Fusion Cryostat zisaba Ultrasonic-Yeza-Yakozwe mbere ya plaque ya Aluminium?

Isiganwa ryisi yose ryo gucuruza ingufu za fonction nucleaire ryerekana isonga ryiterambere ryigenga ryigenga. Hirya no hino muri Amerika ya Ruguru, Uburayi, na Aziya-Pasifika, laboratoire z’igihugu hamwe n’abaterankunga baterwa inkunga na fusion barimo kubaka imashini ifunga rukuruzi Tokamaks hamwe na stellalers zagenewe gutanga ingufu za baseload zikomeza, zidafite karubone.

Imbere yibi bikoresho bya fusion, ubwato bwa cryostat bubamo imbibi zumuriro ukabije. Inzitizi zumuriro mwinshi cyane, zikorera kuri 80 Kelvin (-193 ° C) ukoresheje azote ya azote yuzuye, ikingira ibintu byoroshye bya magnetiki-helium superconducting magnet (ikorera kuri 4 Kelvin) biturutse kubushyuhe bwo hanze buturuka hanze. Izi nzitizi zumuriro zikora mubihe bidasanzwe bya vacuum (10⁻⁶ kugeza 10⁻⁸ Pa). Kuri uru rwego rwimbitse, isuku yubuso bwibibaho byubatswe byerekana imikorere yikigo cyose.

Urusyo rusanzwe rusoza cyangwa intoki zahanaguweho ibyuma byerekana intege nke zica muri fusion cryostats: kwinjiza hydrocarubone munsi yubutaka hamwe no kumeneka kwa microscopique. Kuzunguruka amavuta, gushushanya amavuta, hamwe n ivumbi ryibidukikije byafatiwe mu cyuma cya poro-pore bikora nk ''imyuka idasanzwe.'

Ultrasonic-isukuye kandi yabanje gutunganyirizwa isahani ya aluminiyumu - ikomatanya ibibyimbye bitanga umusaruro mwinshi (nka 6061-T6 na 5083-H111) hamwe na acoustic cavitation ibyiciro byinshi bigenda byangirika hamwe na nano-passivasi idasanzwe - bikemura iki kibazo cyibikorwa. Zikuraho ibinyabuzima bihindagurika cyane, bigabanya gahunda yo kumanura ibyumba byibyumweru, bigahuza neza kurwego rwo hejuru rwa optique ya optique, kandi bikagabanya uburemere bwibintu byubatswe hejuru ya 60% ugereranije ninteko gakondo idafite ibyuma..

Guhitamo Isahani Yuburyo Bwinshi-Vacuum Cryostat Inzitizi

Inzitizi ziterwa nubushyuhe bwa firimu zigomba gukomeza guhura nubushyuhe bwumuriro nimbaraga za electromagnetic imbaraga mugihe gikomeza guhuza neza:

Imbaraga-nyinshi 6061-T6 na 5083-H111 Substrates: Tanga imbaraga zemewe (240 MPa kugeza 275 MPa) kugirango uhangane no kunyeganyega kwa mashini hamwe nimbaraga za magneti zidafite amashanyarazi cyangwa umwobo wihuta.

Cryogenic Toughness kuri 80 Kelvin: Bitandukanye nicyuma cya karubone gihura nimpinduka zangiza ziterwa nubushyuhe buke, latike ya cubic atomique ya aluminiyumu irakomera kandi ikagumana ubukana bukabije ku bushyuhe bwa kirogenike (-193 ° C kugeza kuri -269 ° C), bikarinda gucika amashyanyarazi.

Kugabanuka kwinshi kumpeta zimpande zinyuranye: Imirenge yingabo yumuriro ifite metero nyinshi zumurambararo. Guhindura ibyuma bitagira umuyonga ukagera kuri 2,70 g / cm³ aluminium igabanya toni amagana yuburemere buvuye murwego rusange rushyigikiwe na cryostat, bikagabanya cyane ibyashingiweho byibasiwe na crane hejuru.

Urunigi rwo Kunanirwa kwa Hydrocarubone

Gukoresha amasahani asanzwe yanduye cyangwa intoki zahanaguwe mu kirere cya ultra-high vacuum ibidukikije bitera urunigi rukomeye rwibikoresho byananiranye:

Umutego 'Virtual Leak ' Umutego: Urusyo rusanzwe ruzunguruka amababi asigaje amavuta asigara cyane yinjira mubice bya aluminiyumu. Munsi yumuvuduko wikirere, ayo mavuta akomeza gufatwa; munsi yu cyuho cyinshi, bahora bahumeka, bakarinda vacuum turbopumps kugera kuntego 10⁻⁷ Pa baseline.

Cryogenic Magnet Yanduye: Imyuka ya hydrocarubone yarenze kuri 80K bariyeri yumuriro igenda yerekeza kuri magneti akonje cyane ya 4K. Iyo myuka ikonjesha hejuru yubushyuhe bwa coil, bigatuma amashanyarazi ahagarara kandi bikagira ibyago byo kuzimya magnet.

Gupfundikanya no Kurandura: Niba inzitizi zumuriro zisaba lacquers ya kabiri-emissivitike nkeya, gutwika ifeza, cyangwa imiyoboro ikonjesha ya vacuum, firime ya peteroli ya microscopique irinda guhuza metallurgiki cyangwa imiti itaziguye, bigatuma ibibyimba bihuha kandi bigashishwa mugihe cyamagare yubushyuhe.

Ibibazo

Ikibazo: Kuki gusukura ultrasonic ari itegeko aho guhanagura intoki zo guhanagura ibyapa bya fusion cryostat?

Igisubizo . Umuvuduko ukabije wa ultrasonic cavitation utera amamiriyoni yinjiza mikorobe iturika amavuta hamwe na sub-micron ibice biva muri buri cyorezo cya microscopique, bikagira isuku yukuri ya ultra-high.

Q2: Nigute amavuta azunguruka asigaye atera 'kumeneka kwinshi ' mubyumba byinshi-vacuum?

Igisubizo: Amavuta yafashwe ahumuka gahoro gahoro munsi yumuvu mwinshi (10⁻⁶ kugeza 10⁻⁸ Pa). Mugihe izo molekile zisohoka buhoro buhoro mugihe, sensor ya vacuum yandika imyuka igaragara ya gaze, nubwo ubwato ubwabwo butagira umuyaga mwinshi. Ibi birinda urugereko kugera kumuvuduko wibanze wakazi.

Q3: Niki gituma aluminiyumu ihitamo kuruta ibyuma bitagira umwanda kuri barriost yumuriro wa kirostat?

Igisubizo: Aluminiyumu ikoresha ubushyuhe bwikubye inshuro icumi kurenza ibyuma bitagira umwanda (160–200 W / m · K na 16 W / m · K), bigatuma ingabo zumuriro zikwirakwiza imizigo yubushyuhe buringaniye. Byongeye kandi, aluminium ni bibiri bya gatatu byoroheje, bitari magnetique, kandi bigabanya igihe cya gatanu cya CNC yo gutunganya kugeza 70%.

Q4: Isahani ya aluminiyumu yabanje gutunganywa izongera okiside cyangwa ikuremo ubuhehere mugihe cyo kohereza?

Igisubizo . Inzira ya passivation ikora inzitizi yo gukingira irinda gufata amazi hamwe na okiside yo hejuru mugihe cyo gutwara no kubika ubwiherero.

Q5: Isahani ya aluminiyumu isukuye irashobora kwihanganira ubushyuhe bwa kirogenike kuri Kelvin 80?

Igisubizo: Yego. Imyubakire ya aluminiyumu yubatswe nka 6061-T6 na 5083-H111 igaragaramo isura ya cubic kristaliste itagaragara mu maso idakorerwa ubushyuhe buke. Mubyukuri, imbaraga zabo zitanga imbaraga nimbaraga ziyongera kuri 80 Kelvin mugihe gikomeza guhindagurika no gukomera kuvunika.

Umwanzuro

Kugirango ugure neza kandi ushyireho ultrasonic-yasukuwe mbere yo kuvura isahani ya aluminiyumu ya fusion cryostats:

Manda ASTM E595 Icyemezo cya Ultra-High Vacuum Icyemezo: Saba ibyangombwa byo kugura kugirango ugaragaze ibipimo byemewe (TML <0.10%, CVCM <0.01%) ushyigikiwe na raporo y'ibizamini bya laboratoire ya buri gice kuri buri gice cyakozwe.

Kugaragaza Isuku ya Non-Etch Ultrasonic Cavitation: Saba abayitanga gukoresha ibikoresho byinshi byo gukaraba ultrasonic yogejwe hamwe nogukaraba amazi adahoraho kugirango barebe burundu amavuta yo kwisiga atarinze cyangwa ngo ashyire hejuru yicyapa.

Shimangira ibikoresho byogusukura inshuro ebyiri-Vacuum: Tegeka ko amasahani yose yarangiye agenzurwe mugihe cyisuku, agapfunyika mumifuka yemejwe nuduce duto duto, hamwe nubushyuhe bwa kashe ya azote yapakishijwe inzitizi kugirango yizere ko yanduye akimara kugera ahabigenewe.
