Electron Paramagnetic Resonance (EPR), tseem hu ua Electron Spin Resonance (ESR) yog txheej txheem sib nqus sib nqus uas txheeb xyuas qhov hloov pauv ntawm lub zog hluav taws xob ntawm lub tshuab hluav taws xob tsis sib txuas hauv qhov chaw siv sib nqus.

EPR system feem ntau yog tsim los ntawm cov hlau nplaum, lub tshuab microwave thiab lub tshuab ntsuas hluav taws xob. Cov txheej txheem hlau nplaum feem ntau muab faib ua hluav taws xob, cov hlau nplaum ruaj khov thiab cov hlau nplaum zoo tshaj plaws raws li lub hauv paus ntsiab lus uas lub ntsiab sib nqus sib nqus tsim cov hlau nplaum. Tam sim no, cov hlau nplaum ruaj khov thiab cov tshuab hluav taws xob feem ntau siv.

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

Qhov 0.041T super loj qhib EPR hlau nplaum tsim los ntawm CSJ yog cov hlau nplaum ruaj khov. Cov hlau nplaum ruaj khov tau siv los tsim cov chaw sib nqus zoo ib yam ruaj khov, cov chev chev tau txhawb kom tsim kom muaj kev sib nqus sib nqus, thiab cov kauj hloov pauv tau txhawb kom tsim cov qauv sib nqus sib nqus. Nws ua haujlwm nrog lwm cov khoom siv los tsim hluav taws xob paramagnetic resonance teeb liab, yog li sau cov qauv ntsuas. Kev txheeb xyuas, xwm txheej, thiab lwm yam.
