O meafaigaluega e faʻaaogaina le tekinolosi faʻamalo eletise eletise.Electrons e emitted mai le filament cathode ma taulaʻi atu i totonu o se laʻau o loʻo i ai nei, lea e faʻavaveina e le gafatia i le va o le cathode ma le paʻu e faʻafefe ma faʻafefe ai mea faʻapipiʻi.O loʻo i ai uiga o le maualuga o le malosi ma e mafai ona faʻaumatia le mea faʻapipiʻi ma se mea faʻafefeteina e sili atu i le 3000 ℃.O le ata tifaga e maualuga le mama ma maualuga le lelei o le vevela.
O meafaigaluega ua faʻapipiʻiina i le puna eletise eletise, puna ion, masini mataʻituina mafiafia ata, fausaga faʻasaʻo mafiafia ata ma faʻamautu le faamalu faiga faʻasolosolo mea faigaluega.E ala i le faʻapipiʻiina o le faʻaogaina o le ion, ua faʻateleina le faʻapipiʻiina o le ata, faʻamautu le faʻamaufaʻailoga faʻasolosolo, ma le faʻaalia o le suiga o le galu ona o le susu e aloese mai ai.E mafai ona fa'amautinoaina le toe fa'afouina ma le mautu o le faagasologa o le mafiafia ata tifaga atoa.O lo'o fa'aauupegaina i le fa'ameamea e fa'aitiitia ai le fa'alagolago i tomai o le tagata fa'afoe.
O meafaigaluega e faʻaoga i mea eseese oxides ma mea faʻapipiʻi uʻamea, ma e mafai ona faʻapipiʻiina i le tele-layer precision saʻo ata tifaga, e pei o le ata AR, paʻu galu umi, pasi puʻupuʻu, ata susulu, ata AS / AF, IRCUT, ata ata lanu. , gradient film system, etc. Ua fa'aaogaina lautele i matatioata AR, tioata mata, mea pu'eata, tioata mata, filiga, semiconductor alamanuia, ma isi.
