Super microscope kom pom cov microstructure ntawm cov ntaub ntawv
Tuam Tshoj Spallation Neutron Source yog lub teb chaws loj tshaj plaws kev tshawb fawb thiab thev naus laus zis infrastructure thiab kev tshawb fawb loj loj rau kev siv thoob ntiaj teb kev siv high-tech multidisciplinary. Cov cuab yeej tau sib koom ua ke los ntawm Suav Academy ntawm Kev Tshawb Fawb thiab Xeev Guangdong. Lub koom haum ntawm High Energy Physics ntawm Suav Academy ntawm Sciences yog tus neeg raug cai ntawm qhov project, thiab lub koom haum ntawm Physics ntawm Suav Academy ntawm Sciences koom nrog kev tsim kho.
Rau Tuam Tshoj Spallation Neutron Source, Lub Yim Hli 23, 2018 yog hnub tsis nco qab. Nyob rau tib hnub, Tuam Tshoj Spallation Neutron Source tau dhau qhov kev tshuaj ntsuam xyuas hauv tebchaws thiab tau muab tso rau hauv kev ua haujlwm.
Cov kws tshaj lij los ntawm Pawg Neeg Txais Kev lees paub ntseeg tias txhua qhov ntsuas ntawm Tuam Tshoj Spallation Neutron Source tau mus txog lossis dhau qhov ntsuas pom zoo. Tag nrho cov tsim ntawm cov cuab yeej yog siab heev, qhov zoo ntawm cov cuab yeej kev loj hlob yog zoo heev, lub siab tshaj plaws neutron efficiency ntawm lub hom phiaj chaw nres tsheb thiab cov kev ua tau zoo ntawm peb spectrometers tau mus txog lub thoob ntiaj teb advanced theem.
Nyob rau hauv cov teb twg yuav lub spallation neutron qhov chaw ua lub luag haujlwm? Tus neeg sau xov xwm tau kawm tias Tuam Tshoj tus spallation neutron qhov chaw tau ua tiav ntau qhov kev ua tau zoo hauv accelerators, lub hom phiaj chaw nres tsheb, thiab cov spectrometers, uas tau txhim kho kuv lub teb chaws cov hlau nplaum, cov qib kev txawj ntse thiab kev muaj peev xwm ntawm kev ywj pheej ntawm kev lag luam muaj feem xyuam rau cov khoom siv hluav taws xob, detectors, thiab electronics tau enabled kuv lub teb chaws ua tau ib tug loj leap nyob rau hauv lub teb ntawm high-tam sim no proton accelerators thiab neutron scattering.
"Lub Tuam Tshoj Spallation Neutron Source yog zoo li 'super microscope', qhov kev soj ntsuam zoo tshaj plaws rau kev kawm txog microstructure ntawm cov khoom siv." Chen Hesheng hais.
Tau mus txog qhov ntsuas tsim ntawm 100 kW ib thiab ib nrab xyoo ua ntej ntawm lub sijhawm
Kev xeem dhau qhov kev lees paub tsis tau ua rau cov kws tshawb fawb ntawm Tuam Tshoj qhov chaw spallation neutron, tab sis ua rau lawv muaj kev mob siab ntxiv.
Raws li kev tshaj tawm thiab kev ua haujlwm ntawm cov khoom siv thoob ntiaj teb zoo sib xws, Tuam Tshoj Spallation Neutron Source pib txiav txim siab tias lub zog hluav taws xob yuav ncav cuag tus qauv tsim ntawm 100 kilowatts hauv 3 xyoos tom qab qhov kev lees paub, uas yog, los ntawm Lub Yim Hli 2021.
Txawm li cas los xij, cov kws tshawb fawb riveting tau khoov ntawm kev thawb lub sijhawm mus tom ntej los ntawm kev ua haujlwm hnyav.
Thaum lub Cuaj Hlis 2018, kev khiav hauj lwm nqaj fais fab yog 20 kW; Lub Ib Hlis 2019, nws tau nce mus rau 50 kW; Thaum Lub Kaum Hli 2019, nws tau nce mus rau 80 kW.
Tom qab lub caij nplooj ntoos hlav Festival caij nplooj ntoos hlav xyoo 2020, nyob rau hauv cov xwm txheej ntawm kev tiv thaiv thiab tswj cov kab mob sib kis, cov neeg ua haujlwm kho cov kab hluav taws xob ntawm Dongguan ceg ntawm Lub Tsev Haujlwm Saib Xyuas Hluav Taws Xob, Suav Academy ntawm Kev Tshawb Fawb tau kov yeej cov teeb meem thiab tau pib qhov kev hloov kho tshiab kawg ntawm lub Ob Hlis. 3.
Thaum Lub Ob Hlis 28, lub hom phiaj tua kab hluav taws xob tau mus txog qhov tsim qhov ntsuas ntawm 100 kW, thiab cov nqaj ruaj khov ua haujlwm ntawm 100 kW pib. Lub sijhawm kom ncav cuag tus qauv tsim yog ib thiab ib nrab xyoo ua ntej ntawm qhov kev npaj thawj zaug.
"Txiv qe raws txoj kev" ua rau ntau qhov kev tshawb fawb tseem ceeb
Nws tau tsim, tab sis nws yuav tsum tau siv kom zoo.
Tuam Tshoj Spallation Neutron Source yog tsom mus rau lub ntiaj teb kev cia siab ntawm kev tshawb fawb thiab thev naus laus zis, kev sib ntaus sib tua tseem ceeb ntawm kev lag luam, thiab cov kev xav tau loj ntawm lub teb chaws, thiab tau tsim ntau cov txiaj ntsig kev tshawb fawb tseem ceeb.
Raws li Chen Yanwei, tus lwm thawj coj ntawm lub koom haum ntawm High Zog Physics, Suav Academy ntawm Sciences, nyob rau hauv lub plaub rounds ntawm kev ua tiav los ntawm Tuam Tshoj Spallation Neutron Source, muaj ntau tshaj li 1,500 cov neeg siv sau npe, thiab ntau tshaj 200 cov neeg siv tej yaam num tau ua. ua tiav los ntawm plaub spectrometers. "" "Txoj Kev Sib Txuas Lus" thiab lwm cov ntawv xov xwm tau luam tawm ntau dua 50 cov ntawv, muab kev txhawb nqa rau cov kev xav tau loj ntawm qee lub tebchaws thiab cov kev xav tau ntawm kev lag luam.
Tuam Tshoj tus spallation neutrons txuas ntxiv "nteg qe raws txoj kev".
Nyob rau lub Yim Hli xyoo no, Dongguan ceg ntawm lub koom haum siab zog, Suav Academy ntawm Kev Tshawb Fawb tau ua tiav kuv lub teb chaws tus thawj tus kheej tsim cov khoom siv accelerator boron neutron capture therapy (BNCT) kev sim. Cov cuab yeej BNCT yog ib txoj haujlwm kev lag luam uas siv cov thev naus laus zis ntsig txog ntawm Tuam Tshoj tus spallation neutron qhov chaw. Kev vam meej ntawm cov cuab yeej no tau tsim lub hauv paus rau kev ua haujlwm hauv cheeb tsam thiab kev lag luam ntawm kuv lub teb chaws kho mob BNCT cov cuab yeej kho mob, thiab yuav coj cov thev naus laus zis tshiab rau kuv lub teb chaws kho mob qog noj ntshav.
"Qhov no kuj ua pov thawj tag nrho tias ntxiv rau kev tshawb fawb thiab kev tshawb fawb, kev tsim thiab kev tsim kho ntawm cov cuab yeej siv txuj ci loj yuav txhawb kev loj hlob ntawm kev lag luam muaj feem xyuam thiab thev naus laus zis tshiab." Fu Shinian, tus thawj coj ntawm Tuam Tshoj Spallation Neutron Source Engineering, tau hais.
Tam sim no, Tuam Tshoj Spallation Neutron Source tab tom tsim kev sib koom tes spectrometer, thiab tau thov rau lub teb chaws rau theem ob ntawm kev tsim kho, thiaj li ua tau zoo dua cov kev xav tau ceev ntawm lub teb chaws txoj kev loj hlob lub tswv yim thiab thoob ntiaj teb frontier kev tshawb fawb rau neutron scattering kev tshawb fawb thiab daim ntawv thov. .
