Kev ntseeg tau ntawm -196℃tsis tshwm sim los ntawm kev sib tsoo. Cartridge heaters engineered rau cov kev pabcuam cryogenic suav nrog cov kev txiav txim siab tsim tshwj xeeb thiab kev tsim khoom uas paub qhov txawv ntawm cov khoom lag luam. Kev nkag siab txog cov txheej txheem thev naus laus zis no txhawb nqa cov lus qhia tshwj xeeb thiab daim ntawv thov.
Cov khoom siv tshawb fawb tseem ceeb tsav cov cua sov cua sov tsim. Austenitic stainless steels tuav lub ntsej muag - nruab nrab cov pob zeb siv lead ua uas tiv taus cov pob txha tawg ntawm qhov kub qis. Nickel-raws li alloys muab lwm txoj hauv kev rau kev siv thermal cycling. Resistance hlau cov ntaub ntawv yuav tsum muaj kev ruaj khov resistivity thiab txhua yam khoom nyob rau hauv qhov kub thiab txias.
Insulation system engineering daws cov teeb meem dielectric. Magnesium oxide, cov khoom siv rwb thaiv tsev txheem, yuav tsum tau ua cov kev hloov kho rau cov kev pabcuam cryogenic. Grain loj tis, compaction ntom, thiab ya raws cov ntsiab lus thaum lub sij hawm tsim tag nrho cov cuam tshuam qis - kub dielectric zog. Kev ua haujlwm tshwj xeeb ua kom muaj kev ruaj ntseg ntawm cov khoom siv tsis raug.
Thermal expansion tswj pervades cryogenic tsim. Kev sib txawv ntawm cov ntaub qhwv, rwb thaiv tsev, thiab cov khoom tiv thaiv ua rau muaj kev ntxhov siab sab hauv. Coil winding cov tswv yim, kev txhawb nqa cov qauv, thiab qhov kawg foob tsim kom haum raws li qhov hloov pauv yam tsis muaj kev cuam tshuam hluav taws xob ncaj ncees lossis lub zog txhua yam.
Seal technology sawv cev rau qhov sib txawv tseem ceeb. Txheem epoxy lossis silicone seals ua nruj thiab tawg ntawm qhov kub thiab txias. Iav-rau-cov ntsaws ruaj ruaj hlau, tshwj xeeb ceramic ntsaws ruaj ruaj, lossis cov khoom siv compression ntsaws ruaj ruaj ruaj ntseg hermetic. Kev tsim foob yuav tsum hais txog ob qho tib si thermal cycling thiab ntev - lub sij hawm raug rau cov mob cryogenic.
Manufacturing txheej txheem tswj xyuas kom tsim lub hom phiaj txhais mus rau kev ua hauj lwm teb. Lub rooj sib txoos huv si tiv thaiv kev kis kab mob uas tuaj yeem tsim cov kab hluav taws xob lossis cov pa tawm hauv lub tshuab nqus tsev. Cov txheej txheem vuam tshwj xeeb koom nrog cov ntaub ntawv sib txawv yam tsis tsim cov khoom sib txuas sib txuas. Hauv - kev xeem txheej txheem txheeb xyuas qhov tsis tseem ceeb ua ntej tso cua sov tawm hauv kev tsim khoom.
Kev siv tau zoo rau cov kev pabcuam cryogenic txuas ntxiv dhau qhov kev ntsuas hluav taws xob. Kev ntsuas kub ntawm qhov ntsuas kub, ntsuas qhov ntsuas cua sov, thiab ntsuas qhov ntsuas cua sov ua kom pom tseeb simulate thaj chaw. Cov txheej txheem txheeb cais saib xyuas kev tsim khoom sib xws. Traceability systems sau cov ntaub ntawv thiab cov txheej txheem rau txhua pawg tsim khoom.
Daim ntawv thov engineering txuas hniav tsim muaj peev xwm thiab cov kev xav tau ntawm thaj chaw. Technical kev sab laj txhais cov kev xav tau ntawm lub tshuab ua cua sov specifications. Kev taw qhia kev teeb tsa nyob rau hauv cryogenic{2}} cov kev xav tshwj xeeb. Kev daws teeb meem txhawb nqa kev paub txog kev tsim khoom los daws cov teeb meem hauv cheeb tsam.
Cov txheej txheem txhim kho tas mus li suav nrog kev paub dhau los hauv kev tsim evolution. Kev soj ntsuam tsis ua tiav ntawm cov khoom siv hluav taws xob rov qab los txheeb xyuas cov hauv kev txhim kho. Cov khoom siv thiab txheej txheem kev tsim kho tshiab txhim kho kev ua tau zoo. Cov neeg siv khoom tawm tswv yim txhawb kev txhim kho qhov tseem ceeb.
