Daim ntawv thov tseem ceeb ntawm gadolinium hlau ntawv:
High purity gadolinium hlau ntawv (daim ntawv) yog tsuas yog siv rau magnetic tub yees cov ntaub ntawv thiab neutron activation cov ntaub ntawv.
Cov khoom siv tub yees sib nqus sawv cev los ntawm gadolinium yog ib yam tshiab ntawm cov khoom siv tub yees ntsuab. Nws muaj qhov zoo ntawm kev txo cov pa phem ib puag ncig, pom tseeb lub zog txuag qhov zoo, yooj yim miniaturization, ruaj khov thiab txhim khu kev qha, nyab xeeb thiab ntsiag to, thiab lwm yam, thiab muaj kev loj hlob zoo. Raws li cov khoom siv tub yees sib nqus, gadolinium yog cov khoom siv hlau nplaum sib nqus. Gadolinium muaj zog magnetocaloric nyhuv (MCE) nyob rau hauv chav tsev kub, thiab nws qhov kub thiab txias hloov nrog kev hloov nyob rau hauv magnetic teb zog. Thaum lub sij hawm txheej txheem tub yees, cov khoom sib nqus yuav ua kom sov nyob rau hauv ib qho chaw sib nqus sab nraud vim yog kev taw qhia ntawm cov hlau nplaum dipoles. Thaum lub magnetic teb raug tshem tawm thiab insulated, cov khoom kub txo. GdSiGe alloy muaj Giant Magnetocaloric Effect (GMCE), thiab cov nyhuv magnetocaloric ntawm nws cov khoom siv tub yees sib nqus yog ntau dua li ntawm lwm cov khoom siv sib nqus hlau tub yees hauv thaj chaw kub sib xws. Los ntawm kev kho qhov piv ntawm Si rau Ge hauv gadolinium alloy, Curie kub tuaj yeem hloov pauv tsis tu ncua ntawm 4K thiab 300K.
Cov impurity ntsiab thiab cov pa oxygen nyob rau hauv metallic gadolinium muaj teeb meem heev rau cov nyhuv magnetocaloric. Qhov no yog vim hais tias cov impurities lawv tus kheej thiab qhov nqaim-band cuam tshuam los ntawm impurities cuam tshuam rau kev sib txuas ntawm cov hluav taws xob hauv cov hlau, tshwj xeeb tshaj yog kev sib raug zoo ntawm 4f electrons uas txiav txim siab cov khoom sib nqus, yog li nws muaj kev cuam tshuam tseem ceeb ntawm cov khoom sib nqus thiab cov hlau nplaum. theem, ua rau kev puas tsuaj ntawm thawj-qib sib nqus theem hloov pauv thiab txo qis hauv cov nyhuv magnetocaloric. Lub siab purity gadolinium thiab gadolinium los xij uas tsim los ntawm HNRE tuaj yeem tswj cov ntsiab lus ntawm impurity ntsiab thiab roj cov ntsiab lus raws li qhov yuav tsum tau ua.
Raws li cov khoom siv neutron activation detection, gadolinium foils / nplooj ntawv / phaj yog siv los ntsuas lub cev tsis zoo ntawm cov khoom siv tub rog hluav taws xob simulation teb hauv kev tsim kho nuclear reactor. Lawv yog cov khoom tseem ceeb rau kev ntsuas neutron zog spectrum thiab neutron fluence rate. Raws li tsuas yog lub ntiaj teb tsis tshua muaj qhov profile ntau lawm hauv Suav teb, qhov kev tshawb pom foils / nplooj ntawv tsim los ntawm peb lub koom haum (HNRE) muaj kev ua tau zoo heev thiab tau ua tiav zoo siv hauv cov reactors uas yog Tuam Tshoj lub koom haum ntawm Engineering Physics thiab CNNC, muab kev ywj pheej lav ntawm domestically. tsim cov ntaub ntawv rau txoj kev loj hlob ntawm Tuam Tshoj lub nuclear fais fab kev lag luam. Peb lub koom haum tuaj yeem hloov kho ntau yam tshwj xeeb ntawm cov ntawv tsis tshua muaj hauv ntiaj teb thiab cov ntaub ntawv foil raws li cov neeg siv khoom xav tau.
