Backscattered electrons (BSE) muaj siab-zog electrons originating nyob rau hauv lub electron beam, uas yog reflected los yog rov qab-scattered tawm ntawm cov qauv kev sib tshuam ntim los ntawm elastic scattering kev cuam tshuam nrog Piv txwv atoms.
Dab tsi yog backscattered electrons thiab Secondary electrons?
Cov electrons Backscattered yog rov qab los tom qab kev sib cuam tshuam ntawm cov nqaj thiab cov qauv. Secondary electrons, txawm li cas los xij, pib los ntawm cov atom ntawm cov qauv. Lawv yog qhov tshwm sim ntawm kev sib cuam tshuam ntawm cov kab hluav taws xob thiab cov qauv.
Yuav ua li cas backscattered electrons generated?
Tshuaj dhau los ntawm kev sib cuam tshuam elastic sib cuam tshuam nrog cov atoms hauv cov qauv uas ua rauhauv thawj electron raug rov tawm ntawm cov qauv. Cov electron tau hais tias muaj backscattered (los yog xav rov qab) los ntawm cov qauv. … Backscattered electrons feem ntau muaj lub zog hauv kV ntau.
Yuav ua li cas backscattered electrons qhia rau koj?
Tus naj npawb ntawm cov backscattered electrons mus txog tus ntes yog proportional rau lawv tus lej atomic Qhov kev vam khom ntawm tus lej ntawm BSEs ntawm tus lej atomic pab peb sib txawv ntawm cov theem sib txawv, muab cov duab kos duab. uas yog cov ntaub ntawv ntawm tus qauv muaj pes tsawg leeg.
txhais li cas los ntawm theem ob electrons?
Secondary electrons yog electrons generated as ionization products Lawv hu ua 'secondary' vim lawv yog generated los ntawm lwm yam hluav taws xob (thaum thawj hluav taws xob). Cov hluav taws xob no tuaj yeem ua rau hauv daim ntawv ntawm ions, electrons, lossis photons uas muaj zog txaus, piv txwv li tshaj qhov muaj peev xwm ionization.
