Txhawm rau txhawm rau txhim kho qhov zoo ntawm lub nqaj hlau hauv qhov hluav taws xob, cov cua sov laser pob zeb yob rov qab thiab rov qab raws txoj hauv kev ntawm cov kab nrig ci infrared. Los ntawm hollowing tawm cov nqaj, pab pawg pom tias lawv tuaj yeem tsim cov khoom lag luam zoo dua thiab muaj kev ruaj khov dua.
Cov kev tshawb fawb tshiab qhia tau tias thaum nqaj ntawm cov hluav taws xob tau nthuav dav hauv nruab nrab ntawm lub nplhaib cov nplais laser, cov nqaj ntawm cov kab hluav taws xob tuaj yeem ua rau lub qhov txhab zoo dua thiab ua cov duab hluav taws xob X-ray ntau dua.
Ib pab pawg neeg ntawm zaum npaj ib txoj kev los txhim kho lub electron nqaj thiab tsim ib tug zog X-ray beam: muab ib lub nplhaib rau nws. Pab pawg no suav nrog cov kws tshawb fawb los ntawm Lub Tsev Haujlwm Saib Xyuas Lub Zog 'SLAC National Accelerator Laboratory thiab Stanford University, thiab tau luam tawm lawv cov kev tshawb pom hauv Daim Ntawv Qhia Tawm Physics Rov Los Saib lub hli dhau los.
Ntawm SLAC' s linear accelerator coherent light source (LCLS) thiab lwm yam xoo hluav taws xob tsis muaj hluav taws xob lasers, cov kws tshawb fawb ntsaws thiab ua kom ceev cov hluav taws xob kom ze rau qhov nrawm ntawm lub teeb, thiab tom qab ntawd viav vias lawv rov qab los thiab dhau los ntawm cov hlau nplaum. kom tsim hluav taws xob xoo. Cov xoo hluav taws xob no tau siv los kawm txog kev tshawb fawb lom, tshuaj lom neeg thiab cov khoom siv, kom cov kws tshawb fawb los tsim cov duab qhia siab ntawm lawv cov txheej txheem molecular mus li cas.
Cov kws tshawb nrhiav pom tau tias thaum cov kab hluav taws xob no ntev thiab du (xws li American football), lawv muaj kev ruaj khov tshaj plaws, tuaj yeem tsim cov duab xoo hluav taws xob nrog cov ntsej muag sib npaug ntau dua, thiab tuaj yeem muab cov duab daws teeb meem siab dua. Tab sis vim tias SLAC tus kws tshawb fawb thiab tus kws tshawb fawb tseem ceeb Sergio Carbajo hais tias vim hais tias cov hluav taws xob rov ua ib leeg thaum lawv tsim nyob rau hauv lub tshuab nqus tsev, cov nqaj yuav kawg ua luv luv thiab tsis paub dhau los, zoo li" deflate" Ncaws pob yog them los ntawm spikes."
GG quot; Football Expansion"
Yuav kom daws tau qhov teeb meem no, cov kws tshawb fawb siv cov khoom siv hu ua lub tshuab cua sov, lub tshuab thev naus laus zis tau tshawb fawb ntev los ntawm cov kws sau ntawv hu ua Huang Zhirong Huang thiab Daniel Ratner ntawm SLAC. Lub tshuab cua sov laser khawm cov hluav taws xob nqaj ua hluav taws xob rov qab thiab rov los raws cov kab ntawm txoj kev sib txig infrared laser, tso cai rau cov kws tshawb fawb ua lub ntsej muag ntev dua thiab zoo li tus nqaj. Carbajo hais tias tus txheej txheem no injects zog mus rau hauv lub beam," paub tej chaos li thaum ntxov li sai tau kom tsis txhob ntau lawm kab los ntawm ntxiv chaos."
Nws hais tias:" Peb lub tswv yim yog tias yog peb tsis ua dabtsi nrawm rau thiab ncaws pob ncaws pob, thiab tom qab ntawd xa mus rau cov kab nrawm nrawm, qhov tsis txaus ntseeg yuav nthuav dav thiab cov nqaj zoo yuav xeb," Nws hais tias." Txawm li cas los, yog hais tias peb' tshav kub' lub tshuab hluav taws xob thiab hloov nws txoj kev faib hluav taws xob thaum pib, peb tuaj yeem hloov kho nws cov duab los txhim kho nws qhov loj thaum nws mus txog qhov kawg ntawm lub nrawm nrawm."
GG quot; Donut Laser"
Hauv txoj kev tshawb nrhiav tshiab no, pawg neeg tshawb xyuas tau txhim kho cov cuab yeej los ntawm hollowing tawm cov kab teeb ci laser mus rau hauv lub nplhaib zoo li" donut laser." Lub tshuab hluav taws xob tshiab tsim hluav taws xob no tuaj yeem txhim kho qhov tsis sib xws thiab tsim qhov nqaj ruaj khov dua, vim tias nws yuav co cov hluav taws xob sib txawv raws li yuav ua li cas cov xaim hluav taws xob ze rau ntawm nruab nrab ntawm lub nplhaib. Qhov kawg no yog ib txig zoo li tus football haum rau ya nyob rau hauv tej subatomic Super tais.
GG quot; Qhov no technology pab txoj kev zuag qhia tag nrho ntawm cov electron nqaj," Carbajo hais tias." Nws muab cov kev tswj qhov tseeb ntawm cov qauv ntawm cov kab hluav taws xob, yog li nws muaj qhov tseem ceeb hauv kev nthuav dav hauv kev ua kom nrov ntawm kev ua haujlwm ntawm cov twj siv hluav taws xob uas cia siab rau cov khoom siv hluav taws xob (xws li cov nplhaib cia, cov kab nrawm nrawm thiab lub teeb ci).
