Particle accelerators siv hluav taws xob teb kom nrawm thiab nce lub zog ntawm lub nqaj ntawm cov khoom , uas yog steered thiab tsom los ntawm magnetic teb. Cov particle qhov chaw muab cov cov khoom , xws li asprotons lossis electrons, uas yuav tsum tau nrawm.
Xav txog qhov no, cov particle accelerators mus sai npaum li cas?
Particle accelerators tsis txhob maj nrawm cov khoom ; lawv thiab ua lawv loj heev. AsEinstein tau kwv yees hauv nws txoj kev xav ntawm kev sib raug zoo, tsis muaj particle uas muaj huab hwm coj tuaj yeem taug kev raws li ceev raws li cov ceev oflight-li 186,000 mais ib ob.
Dab tsi yog particle accelerator rau dummies? A particle accelerator yog ib qho khoom siv uas siv cov hlau nplaum muaj zog los ua kom nrawm nrawm ntawm lub teeb cov khoom mus txog incredibly ceev ceev thiab ces collides nws nrog ib tug nqaj ntawm cov khoom mus rau lwm txoj kev.
Ib yam li ntawd, nws raug nug, vim li cas peb thiaj li siv cov khoom accelerators?
A particle accelerator yog lub tshuab uas siv electromagnetic teb rau propel them cov khoom mus rau high speeds thiab energies, thiab kom muaj nyob rau hauv zoo-txhais kab teeb. Loj accelerators yog siv forbasic tshawb fawb hauv particle physics. Electrostatic accelerators siv static hluav taws xob teb kom nrawm cov khoom.
Particle accelerators nyob qhov twg?
Electron thiab qis siv hadron accelerators
| Accelerator | Qhov chaw | Accelerated particle |
|---|---|---|
| Tsawg Zog Antiproton Ring | CERN | Antiprotons |
| Cambridge Electron Accelerator | Harvard University thiab MIT, Cambridge, MA | Hluav taws xob |
| SLAC Linac | SLAC National Accelerator Laboratory | Electron / Positron |
| Fermilab Booster | Fermilab | Protons |

Cov haujlwm ua haujlwm li cas hauv lej?
Hauv kev ua lej, kev ua haujlwm yog qhov kev sib raug zoo ntawm cov teeb tsa uas koom nrog txhua lub ntsiab lus ntawm thawj zaug raws nraim ib qho ntawm cov txheej thib ob. Cov piv txwv zoo yog cov haujlwm los ntawm cov lej mus rau cov lej lossis los ntawm cov lej tiag mus rau cov lej tiag. Piv txwv li, txoj haujlwm ntawm lub ntiaj teb yog lub luag haujlwm ntawm lub sijhawm
Yuav ua li cas koj nrhiav tau tus nqi ntawm ib tug particle?
Nyob rau hauv physics, ib tug nqi particle yog ib tug particle nrog ib tug hluav taws xob nqi. Tej zaum nws yuav yog ib qho ion, xws li cov molecule los yog atom nrog ib qho nyiaj seem lossis tsis txaus ntawm cov electrons txheeb ze rau protons. Nws kuj tuaj yeem yog electron lossis proton, lossis lwm yam khoom siv hauv tsev, uas txhua tus ntseeg tias muaj tib yam nqi (tshwj tsis yog cov tshuaj tiv thaiv)
Koj ua li cas magnetic particle soj ntsuam?
VIDEO Hais txog qhov no, dab tsi yog lub hauv paus ntsiab lus ntawm kev ntsuam xyuas magnetic particle? Cov magnetic particle kuaj Cov txheej txheem ntawm Kev Tshawb Fawb Tsis Muaj Kev Tshawb Fawb tau tsim nyob rau hauv Tebchaws Meskas, xyoo 1930, ua ib txoj hauv kev los xyuas cov khoom siv hlau ntawm cov kab ntau lawm.
Lub luag haujlwm ntawm txhua qhov particle hauv ib lub atom yog dab tsi?
Cov khoom uas me dua lub atom hu ua subatomic particles. Peb lub ntsiab subatomic particles uas tsim ib lub atom yog protons, neutrons, thiab electrons. Qhov chaw ntawm lub atom hu ua lub nucleus
Cov txheej txheem dab tsi yog lub luag haujlwm rau txoj haujlwm ua haujlwm sib txawv?
Position-effect variegation (PEV) tshwm sim thaum cov noob ib txwm nyob hauv euchromatin yog sib xyaw nrog heterochromatin los ntawm kev hloov kho lossis hloov pauv. Thaum lub ntim ntim heterochromatin kis thoob plaws heterochromatin / euchromatin ciam teb, nws ua rau kev hloov pauv ntawm kev ntsiag to hauv tus qauv stochastic
