electron microscope kua txias daim ntawv thov

Lub tshuab electron microscope yog tsim los ntawm lub lens chim, lub tshuab nqus tsev thiab lub hwj chim txee. Lub lens fwj feem ntau suav nrog cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov qauv khib nyiab, cov tshuaj ntsuam fluorescent, cov khoom ntes thiab lwm yam khoom, uas feem ntau yog sib sau ua ke rau hauv ib kem los ntawm sab saum toj mus rau hauv qab. Lub tshuab nqus tsev yog siv los xyuas kom meej lub tshuab nqus tsev hauv lub tshuab ntsuas kom tsis txhob nqus cov electrons los yog tsis ncaj ncees lawm ntawm nws txoj kev. Nws yog tsim los ntawm cov tshuab nqus tsev twj tso kua mis, lub twj tso kua mis diffusion thiab lub tshuab nqus tsev vacuum, thiab txuas nrog lub lens chim los ntawm cov yeeb nkab tawm cua. Lub hwj chim txee yog tsim los ntawm high voltage generator, excitation tam sim no regulator thiab ntau yam kev cai thiab tswj units.

Thaum lub tshuab hluav taws xob siv hluav taws xob ua haujlwm, nws yuav tsim hluav taws xob loj, thiab qhov chaw ntawm cov cua sov yog lub hwj chim txee. Qee cov neeg siv feem ntau teb tias qhov kub thiab txias nyob rau lub caij ntuj sov, uas cuam tshuam rau kev ua haujlwm zoo thiab raug. Qhov kev ncua deb ntawm cov khoom siv thiab cov khoom siv hluav taws xob ntawm cov khoom siv hluav taws xob microscope yog nyob ze, thiab qhov chaw tshav kub dissipation yog me me. Yog li ntawd, kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov kub hauv tsev kom nws nyob rau hauv 25 ± 2 degree. Rau qee qhov cua sov dissipation, vim tias lawv muaj cov khoom siv hluav taws xob thiab txais yuav cov cua kub cua sov, ua tib zoo saib xyuas kom qhov chaw nyob ze lawv tsis muaj kev cuam tshuam. Nyob rau tib lub sijhawm, tsis txhob muab cov khoom tso rau ntawm daim npog npog ntawm qhov chaw los cuam tshuam cov cua sov dissipation.

electron microscope heat dissipation

Ntawm qhov tod tes, cov thev naus laus zis cua sov tshiab tuaj yeem xav txog. Piv txwv li, lquid cooling heat dissipation tuaj yeem siv rau lub tshav kub dissipation ntawm electron microscope. Cov yam ntxwv uas ntsiag to, ua haujlwm tau zoo thiab lub neej ntev ntawm cov kua dej txias qhib rau txoj hauv kev tshiab rau cov tshuab cua sov dissipation. Yog li ntawd, cov kua ua kua txias yuav siv tau ntau dua thiab ntau dua hauv cov khoom siv high-precision.
