Cov kws tshawb fawb ntawm Rossendorf Research Center hauv Helmholtz Dresden, Lub teb chaws Yelemees, tau ua tiav qhov tseem ceeb hauv laser plasma acceleration. Siv cov txheej txheem tshiab, lawv tau ua tiav hauv kev ua kom lub zog proton ntawm li 80 txog 150 mega-electron volts. Qhov tshwm sim no ua tau zoo tshaj cov ntaub ntawv dhau los rau proton acceleration thiab tso cai rau cov laser me me kom ua tiav, thawj zaug, lub zog theem tam sim no tsuas muaj nyob hauv ntau qhov chaw loj dua. Qhov kev tshawb fawb zaum kawg no yuav tsum ua kom cov tshuaj thiab cov ntaub ntawv tshawb fawb. Cov ntawv no tau luam tawm nyob rau hauv 13th qhov teeb meem ntawm Nature Physics.
Txoj kev tshiab no ua rau kom lub zog ntawm proton acceleration ntawm laser pulses (cov duab kos duab). Duab qhov chaw: Helmholtz Rosen Research Center Dresden, Lub teb chaws Yelemees
Piv nrog rau cov tsoos accelerators, laser plasma accelerators tsis tso siab rau cov xov tooj cua muaj zog los txhawb cov khoom, tab sis siv lasers kom nrawm cov khoom. Txawm li cas los xij, cov thev naus laus zis no tam sim no nyob rau theem kev tshawb fawb, thiab tsuas muaj ob peb lub tshuab laser loj heev hauv ntiaj teb uas tuaj yeem ua kom cov protons mus rau qib zog ntawm 100 MeV.
Tus thawj coj tshawb fawb Tim Ziegler tau hais tias txhawm rau kom ua tiav cov txiaj ntsig zoo sib xws siv cov khoom siv laser me thiab cov pulses luv dua, lawv tau siv qhov zoo ntawm cov yam ntxwv ntawm laser flashes, uas yog, ib feem me me ntawm lub laser ua zoo li "dhia pib" ntawm lub Ib tug series ntawm complex acceleration mechanisms yog triggered nyob rau hauv lub tshwj xeeb yas ntawv ci. Qhov no ua rau kom cov proton acceleration zog ntawm lub laser hu ua DRACO.
Kev tshawb fawb tau pom tias yav dhau los proton acceleration zog cov ntaub ntawv ntawm DRACO laser yog hais txog 80 MeV, thiab tam sim no nws muaj peev xwm ncav cuag 150 MeV, yuav luag ob zaug ntawm thawj. Tsis tas li ntawd, cov kab hluav taws xob nrawm nrawm nthuav tawm cov yam ntxwv zoo kawg nkaus ntawm lub zog siab thiab kev txav tsis sib xws.
Pab neeg tshawb fawb ntseeg tias qhov kev ua tiav no yuav tsum ua kom cov laser plasma accelerators me me los ua lub luag haujlwm tseem ceeb hauv kev kho mob, tshwj xeeb tshaj yog hauv cov kev kho mob qog nqaij hlav. Cov kws kho mob tam sim no tso siab rau cov kws kho mob loj los ua cov kev tshawb fawb no. Cov khoom siv hluav taws xob loj uas twb muaj lawm siv lub zog loj, thiab laser plasma accelerators tuaj yeem siv nyiaj ntau dua. Laser flashes tseem tuaj yeem siv los tsim cov neutron pulses luv thiab khaus, uas yog qhov tseem ceeb rau kev tshawb fawb thiab thev naus laus zis thiab kev tshuaj xyuas cov ntaub ntawv.
