Kupita patsogolo kwambiri kwa Ultraviolet Kuwala

Kupita patsogolo kwambiri muyeso ultravioletukadaulo wopepuka

M'zaka zaposachedwa, ma eltraviolet a Hartraviolet High, adakopa chidwi kwambiri ndi magetsi a Electronics chifukwa chogwirizana kwambiri, nthawi yayitali. Ndi kupititsa patsogolo ukadaulo, izigwero loyeraikupanga njira yobwereza zobwerezabwereza zobwerezabwereza, kukweza zithunzi zapamwamba, mphamvu zapamwamba za Photon ndikufupikirana. Izi sizimangotha ​​kukhathamiritsa kuthetsa kukula kwa ma estraviolet magwero, komanso amapereka mwayi watsopano wa chitukuko chamtsogolo katswiri. Chifukwa chake, kuphunzira mozama komanso kumvetsetsa pafupipafupi kubwereza kwamphamvu kwamphamvu kwa ultraviolet ndikofunikira kwambiri pakuphunzira ndi kugwiritsa ntchito ukadaulo wodula.

Pazolinga za Electron Spectropy pa femturosecond ndi masikelo a nthawi, kuchuluka kwa zochitika zomwe zimayesedwa pamtengo umodzi nthawi zambiri sizingatheke, kupanga mawonekedwe otsika mtengo kuti mupeze ziwerengero zodalirika. Nthawi yomweyo, kuwunika kotsika ndi zithunzi zotsika kumachepetsa chiwerengero cha zizindikiro za microscopic poyerekeza ndi nthawi yochepa. Mwa kufufuza mosalekeza ndi zoyeserera, ofufuza asintha kwambiri pakubwezeretsa ndalama ndi kapangidwe kake kobwerezabwereza kwamphamvu kwa ultraviolet. Tekinolojeni yotsogola yomwe imaphatikizidwa ndi pafupipafupi kubwereza kwamphamvu kwambiri kwa ultraviolet yakhala ikugwiritsidwa ntchito kukwaniritsa chowonjezera chazinthu zachilengedwe komanso zamagetsi.

Ntchito za magwero a Ultraviolet Kuwala, monga mawonekedwe a elelropyctrocycycopy (ma arpes), amafuna mtengo wowonjezereka kwa ultraviolet kuti muunikire zitsanzo. Ma elekitironi pamalo a sampuli amasangalala kwambiri ndi kuwala kosalekeza ndi kuwala kwa ultraviolet, ndi magetsi a kinetic ndi kutulutsa kwa zithunzi za ziwonetsero za zitsanzo. Chiwonetsero cha Seclenrizer yokhala ndi njira yothetsera vuto la angle amalandila zowotchera zowotchera ndikupeza gululi pafupi ndi gulu la valence. Pafupipafupi kubwereza kochepa kwa ultraviolet, chifukwa muyeso umodzi wake umakhala ndi zithunzi zambiri, zimasangalatsa kuchuluka kwa potolectroctron Kineeton Kineeton. Kuti muchepetse mphamvu ya Space Persey, ndikofunikira kuchepetsa zojambula zomwe zili mu phula lililonse ndikusungabe chithunzithunzi, motero ndikofunikira kuyendetsalaserNdi pafupipafupi kubwereza zokolola kuti mupange gwero lowunikira lomwe lakhala ndi pafupipafupi.

Kubwerera kwaukadaulo Waukadaulo kumazindikira kuti m'badwo wa ma harmonics obwereza ku MHZ
Kuti mupeze gwero lowopsa la ultraviolet ndi 60 Mhz, gulu la a Jones ku Yunivesite ya Briteni ku United Kingland kuyesa. Kuwala kumatha kubweretsa ziwerengero zopitilira 1011 pa sekondi imodzi ndi mgwirizano umodzi pazaka zobwereza 6 mpaka 40 EV. Anagwiritsa ntchito makina osungirako a yTerbium-doptebium ngati mbeu ya FSEC, komanso mikhalidwe yoyendetsedwa ndi ma purse yopangidwa kudzera mu ntchentche yopanga ma ntchentche (fceo) phokoso ndikusunga matumba abwino kumapeto kwa mawonekedwe a trelifari. Kuti mukwaniritse zowonjezera zokhazikika mkati mwa FSEC, amagwiritsa ntchito zolaula zitatu za serco kuti zitheke, ndipo nthawi yoyendayenda pamagetsi, ndipo vnnulopu yonyamula gawo.

Pogwiritsa ntchito gasi ya Krypton ngati mpweya wogwira ntchito, gulu lofufuzira lidachita m'badwo wa ma harimonics apamwamba kwambiri ku FSEC. Amachita miyeso ya ar-marpes a graphite ndipo adawonanso kutentha kwa magetsi komanso kubwezeretsa pang'onopang'ono kwa anthu osangalatsidwa ndi elertron, komanso mphamvu zosakhala ndi mizere ya Fermi pamwamba pa 0,6 EV. Izi zimapereka chida chofunikira pophunzira kapangidwe kake. Komabe, m'badwo wa ma harmonics okwera mu FSEC ali ndi zofunikira kwambiri pakukuyenerera, kuperekera ndalama, zomwe zimapangitsa kuti zitseke zikuluzikulu, zomwe zimakhudza kulimbikitsa kwakukulu, zomwe zingakhudze pang'onopang'ono. Nthawi yomweyo, nthawi yopanda mawu ya plasma padera lomwe limayang'aniridwanso ndi zovuta. Chifukwa chake, pakadali pano, mtundu wamtunduwu sudzakhala chachikulu kwambirigwero lalitali kwambiri.
