Electron Paramagnetic Resonance (EPR), tseem hu ua Electron Spin Resonance (ESR) yog cov txheej txheem sib nqus resonance uas kuaj pom cov kev hloov pauv ntawm lub zog ntawm lub zog ntawm cov hluav taws xob tsis sib xws hauv qhov chaw sib nqus.

EPR system feem ntau yog tsim los ntawm cov hlau nplaum, lub tshuab microwave thiab cov khoom siv hluav taws xob. Lub tshuab hlau nplaum feem ntau muab faib ua electromagnets, cov hlau nplaum ruaj khov thiab cov hlau nplaum superconducting raws li lub hauv paus ntsiab lus uas lub ntsiab magnetic teb generates magnetic teb. Tam sim no, cov hlau nplaum ruaj khov thiab electromagnet feem ntau yog siv.

Cov hlau nplaum ruaj khov tuaj yeem tswj tau cov hlau nplaum tas mus li, lawv cov nqi tsim kho thiab kev saib xyuas yog qhov tsawg, thiab lawv tuaj yeem tsim kom qhib thiab loj hauv txoj kab uas hla, uas yog qhov zoo rau cov neeg mob claustrophobia.

0.041T super loj qhib EPR hlau nplaum tsim los ntawm CSJ yog cov hlau nplaum ruaj khov. Cov hlau nplaum tas mus li yog siv los tsim kom muaj qhov sib nqus zoo li qub, lub cheb coil yog lub zog los tsim kom muaj qhov sib nqus sib nqus, thiab cov qauv hloov pauv tau ua kom muaj zog los ua kom muaj qhov sib nqus sib nqus. Nws ua haujlwm nrog lwm cov khoom siv los tsim hluav taws xob hluav taws xob paramagnetic resonance teeb liab, yog li tsim cov qauv ntsuas. Analysis ntawm, xwm txheej, thiab lwm yam.
