Superconducting Niobium Qws thiab Daim Ntawv Qhia

Lub superconducting Xov tooj cua zaus (RF) kab noj hniav siv nyob rau hauv cov dawb electron lasers yog tsim los ntawm siab purity niobium nrog siab Residual Resistivity Ratio (RRR). Niobium superconducting Residual Resistivity Ratio (RRR) txhais tau tias yog qhov piv ntawm niobium superconducting resistivity thiab kub kub superconducting niobium resistivity nyob rau hauv chav tsev kub. Nrog rau qhov nce ntawm cov khoom siv purity thiab txo cov kev ntxhov siab sab hauv, RRR tus nqi txo. RRR tus nqi tuaj yeem siv los ntsuas purity ntawm cov hlau. SSC tuaj yeem tsim cov khoom niobium raws li tus nqi RRR cov neeg siv khoom xav tau. RRR niobium feem ntau yog tsim los ntawm tus pas nrig thiab daim ntawv. Cov khoom hauv ingot thiab raj kuj muaj nyob ntawm kev thov.

Tsis tas li ntawd, niobium titanium alloys yog siv los ua hom II superconductor cov ntaub ntawv rau superconducting hlau nplaum. Daim ntawv thov ntawm cov hlau nplaum superconducting muaj xws li magnetic resonance imaging thiab nuclear magnetic resonance instruments, thiab hauv particle accelerators. Cov alloys feem ntau muaj nrog 47 feem pua, 50 feem pua, thiab 55 feem pua titanium. Thov hu rau peb kom paub meej ntxiv.
