A SQUID yog lub ntsuas hluav taws xob zoo heev siv los ntsuas qhov sib nqus sib nqus tsis tshua muaj zog, raws li cov khoom siv hluav taws xob loj uas muaj Josephson junctions. SQUIDs rhiab txaus los ntsuas cov teb tsawg li 5 × 10⁻¹⁴ T nrog ob peb hnub ntawm qhov ntsuas nruab nrab. Lawv cov suab nrov tsawg li 3 fT·Hz⁻¹⁄².

SQUID magnetometer ua haujlwm li cas?

Lub cuab yeej yuav raug teeb tsa ua lub ntsuas hluav taws xob txhawm rau kuaj pom cov hlau nplaum me me me txaus los ntsuas cov hlau nplaum hauv cov kab mob nyob …. Thaum tus qauv txav mus los nws tsim ib qho sib nqus sib nqus flux nyob rau hauv lub pick-up coil.

SQUID physics yog dab tsi?

Superconducting Quantum Interference Device (SQUID) magnetometry. A SQUID yog ib lub cuab yeej uas yog siv los ntsuas qhov ntsuas qhov sib nqus me me hloov pauv. Nws yog raws li kev ua haujlwm theoretical ntawm Josephson thiab tau sim ua tiav hauv xyoo 1963.

SQUID method yog dab tsi?

Scanning SQUID microscopy yog ib qho txheej txheem uas lub tshuab hluav taws xob quantum cuam tshuam (SQUID) yog siv rau cov duab saum npoo sib nqus lub zog nrog micrometer scale daws teeb meemIb qho me me SQUID yog mounted rau ntawm lub ntsis uas yog ces rastered nyob ze ntawm qhov chaw ntawm tus qauv yuav tsum tau ntsuas.

SQUID sensors ua haujlwm li cas?

SQUID sensor ua haujlwm li cas? … Txhua SQUID muaj ib lub voj macroscopic superconducting nrog ib lossis ob qhov txuas tsis muaj zog (Josephson Junctions). Thaum txias txias hauv qab qhov ntsuas kub tseem ceeb, cov hlau nplaum sib nqus yuav raug kaw hauv lub voj Cov tam sim no super (isupra) ua rau cov hlau nplaum sib nqus ua ntau yam ntawm fluxoid Φ0
