TWI CLOSECOSECOMB X-ray Pulse laser
Assoticond x-rayPulse laserNdi mphamvu yayikulu ndi nthawi yayifupi ya pulse ndiye chinsinsi choti mukwaniritse zomwe sizimachitika osagwirizana ndi X-ray kuphatikiza. Gulu lofufuzira ku United States linagwiritsa ntchito njira ya magawo awiriX-ray free alertron lasersKutulutsa mwanzeru anderte. Poyerekeza ndi malipoti omwe alipo, mphamvu yapakati pa ma pulose zimachuluka ndi dongosolo la kukula, mphamvu yayikulu kwambiri ndi 1.1, ndipo mphamvu ya pakati pa 100 μj imapitilira 100 μj. Phunziroli limaperekanso umboni wokwanira woti abweretse maulendo apamwamba a X-ray.Mphamvu zamagetsiayendetsa madera ambiri atsopano a kafukufuku, kuphatikiza sayansi yam'munda, artonecond speptroscopy, ndi ma asser tinthu othamanga. Mwa zina zonse za ma lasers, ma ray a ma X-ray amagwiritsidwa ntchito kwambiri pakuzindikira zamankhwala, kupezeka molakwika mafakitale, kuyendera chitetezo ndi kafukufuku wasayansi. Ma laser a X-ray a elect a elect (xfel) amatha kuwonjezera mphamvu ya ma X-ray kudzera mumitundu ingapo ya umisiri wa X-Ray A Sportcond Opambana XFELORD NTHAWI YABWINO KWAMBIRI MU SATTOOMCOnd Science ndi Teak

Ma Lasers Omasulira a Intractonimatha kupeza mphamvu zambiri zamphamvu kwambiri kuposa kuchuluka kwa chilengedwe chogwiritsa ntchito kusakhazikika kwa malo ophatikizika, komwe kumachitika chifukwa chopitilira njira ya ma radiation mu mawonekedwe a elekitironi ndi magnetictor. Mu mtundu wolimba wa x-ray (pafupifupi 0,01 nm mpaka 0.1 NM Hilllength), kupezeka ndi masitepe ophatikizika ndi njira zolumikizira. Mu gawo lofewa la X-ray (pafupifupi 0,1 nm mpaka 10 NM Hilllength), kukhazikitsidwa ndi kaphikidwe kaphikidwe. Posachedwa, assotiond purses ndi mphamvu ya 100 GW yanenedwa kuti ipangidwire pogwiritsa ntchito njira yodzikulitsa yodziwika bwino.

Gulu lofufuzira linagwiritsa ntchito dongosolo la magawo awiri ophatikizira xfel kuti akweze kutulutsa kwa X-raygwero loyerakumapiri, dongosolo la kusintha kwakukulu kwa zotsatira za mawu. Kukhazikitsa koyeserera kumawonetsedwa pa Chithunzi 1. Kutengera kwa njira ya esose, mawonekedwe a Photocamalide amasinthidwa kuti athe kupeza mtengo wamagetsi, ndipo amagwiritsidwa ntchito popanga mafinya a x-ray. Choyambirira chapezeka kutsogolo kwa mtengo wamagetsi, monga akuwonetsera pakona yakumanzere kwa 1. Mtengo wa elekitroni umachedwa ndi mitengo ya elector yomwe siyikusinthidwa kapena kusokonekera. Pomaliza, maginito achiwiri amagwiritsidwa ntchito kukulitsa X-rays kudzera mu kulumikizana kwa artbond purses ndi gawo latsopano.

CHITH. 1 Chizindikiro choyesera; Fanizoli likuwonetsa gawo lalitali la gawo (nthawi yayitali ya electron, wobiriwira), mbiri yakale (yamtambo), ndipo radiation yomwe imapangidwa ndi maphulidwe oyamba (ofiirira). Xtcav, x-band zopingasa; CVMI, Coaxial Propping System; Fzp, fresnen band protemerometer

Onse opindika amapangidwa chifukwa cha phokoso, kotero mawonekedwe aliwonse ali ndi mawonekedwe osiyanasiyana komanso nthawi yomwe akatswiri ofufuzawo adayamba mwatsatanetsatane. Pankhani ya spectra, adagwiritsa ntchito chojambula cha gulu la Fresnen kuti ayesetse mawonekedwe a munthu wofanana, ndipo adapeza kuti izi zikakhala zosalala, zomwe zikuwonetsa kuti ma puller sanasinthe. Munthawi yochepa, burnger fe ya angular imayezedwa ndipo nthawi yamatayi imadziwika. Monga taonera Chithunzi 1, kuyika kwa X-ray kumakutidwa ndi zozungulira zozungulira zopingasa zotupa za laser. Zojambulajambula zokhala ndi zojambula za X-ray zimapanga zing'onozing'ono polumikizana ndi vekitala zomwe zingatheke. Chifukwa gawo lamagetsi la laser limazungulira ndi nthawi, kufalikira kwa Photomelectron kumatsimikizika ndi nthawi ya election yopanda kanthu, komanso ubale pakati pa njira yogawika ya mbendera komanso kufalikira kwa chithunzithunzi kwa chithunzi. Kugawidwa kwa Photoelectron Mutume kumayesedwa pogwiritsa ntchito mapu othamanga a Coaxial akuganiza zowoneka bwino. Kutengera magawo ndi zotsatira za ziwonetserozo, zomwe zimachitika nthawi yayitali za artfoosecand zopindika zitha kumanganso. Chithunzi 2 (a) chikuwonetsa kugawa kwa nthawi yayitali, ndi pakati pa 440. Pomaliza, wotchinga yamagetsi imagwiritsidwa ntchito kuyeza mphamvu zamkati, ndipo kuchuluka kwa kuchuluka kwa mphamvu ya peak ndi nthawi yokomera monga tikuonera pa Chithunzi 2 (b) adawerengedwa. Kusintha katatu kumagwirizana ndi mitengo yosiyanasiyana ya electron, yokhazikika yolimba ndi magremic compresor mochedwa mikhalidwe. Zosintha zitatuzo zimapereka mphamvu zambiri za 150, 200, ndi 2600 μj, motero, ndi mphamvu yayikulu ya 1.1.

Chithunzi 2. (b) Kubalalitsa chiwembu chofanana ndi mphamvu ya Peak

Kuphatikiza apo, kafukufukuyu nawonso adawoneranso zochitika za Solomoni - monganso gulu la X-ray, lomwe limawoneka ngati kufupikira kwamphamvu pakukula kwa makulima. Zimayambitsidwa ndi kulumikizana kwamphamvu pakati pa ma elekitoni ndi radiation, chifukwa mphamvu idasamutsidwa mwachangu kuchokera ku elekitoni kumutu wa X-ray kukwiridwa ndi elekitironi kuchokera mchira wa pulse. Mwa kuphunzira mozama za izi, zikuyembekezeka kuti mafinya a X-ray omwe ali ndi nthawi yochepa kwambiri komanso mphamvu yapamwamba kwambiri imatha kudziwitsidwa ndikuwonjezera njira yotsatsira ndikugwiritsa ntchito njira.
