CERN, Lub Koom Haum European rau Kev Tshawb Fawb Txog Kev Tshawb Fawb, tau tshaj tawm qhov kev sib tw hauv kev thauj cov tshuaj tiv thaiv. Cov kws tshawb fawb ntawm CERN tau ua tiav kev sim thauj cov protons thoob plaws nws lub tsev kawm ntawv tshawb fawb, tso lub hauv paus rau kev nyab xeeb txav cov tshuaj tiv thaiv yav tom ntej.
Cov ntawv xeem no yog ib feem ntawm BASE-STEP (Baryon Antibaryon Symmetry Experiment, Symmetry Tests in Experiments with Portable Antiprotons) kev sim, tsim los tshawb nrhiav cov txheej txheem nqa tau yooj yim rau kev ntim thiab xa khoom antimatter. Cov kws tshawb fawb tau siv cov protons ua qhov sawv ntsug, tab sis qhov kev sim ua tiav yog ib kauj ruam tseem ceeb rau pem hauv ntej. "Yog tias koj tuaj yeem ua nws nrog protons, nws tseem yuav ua haujlwm nrog cov tshuaj tiv thaiv," said Christian Smorra, tus thawj coj ntawm qhov project.
Dab tsi ua rau kev thauj mus los antimatter nyuaj?
Antimatter, daim iav rov qab ntawm cov teeb meem tsis tu ncua, rhuav tshem thaum sib cuag nrog cov teeb meem, tso lub zog. Qhov no ua rau nws nyuaj heev rau khaws cia, kawm, thiab thauj. Vim yog cov kev txwv no, kev sim nrog cov tshuaj tiv thaiv tau raug kaw rau CERN's Antiproton Decelerator txog tam sim no. Lub peev xwm los thauj cov khoom zoo li no tuaj yeem qhib qhov muaj peev xwm tshiab rau kev sim ua kom raug ntawm cov chaw sim sab nraud.
Qhov kev sim tsis ntev los no koom nrog kev thauj huab cua ntawm 70 protons hauv cov cuab yeej tshwj xeeb sib nqus, txias kom ze rau qhov tsis muaj tseeb, thiab muab tso rau hauv lub tsheb thauj khoom. Qhov teeb tsa tau tswj hwm qhov kev ruaj ntseg nyob thoob plaws 3.7-kilometer txoj hauv kev hauv CERN tsev kawm ntawv. Cov kws tshawb fawb tau saib xyuas lub kaw lus ze kom paub meej tias tsis muaj kev poob thaum lub sijhawm ua haujlwm ntau teev. Lub kaw lus siv cov thev naus laus zis cryogenic siv los ntawm cov roj teeb thiab helium txias, ua rau nws compact thiab portable.
Qhov kev puas tsuaj no txhais li cas rau physics thiab dhau mus
Qhov cuam tshuam ntawm qhov kev ua tiav no yog nyob deb heev. Yog tias yoog rau cov tshuaj tiv thaiv, qhov system no tuaj yeem ua rau xa mus rau cov chaw soj ntsuam precision thoob plaws Tebchaws Europe. Ib qho ntawm thawj lub hom phiaj yog thauj cov tshuaj tiv thaiv mus rau Heinrich Heine University hauv Düsseldorf, Lub teb chaws Yelemees, rau kev kawm qib siab.
Cov kev txhim kho zoo li no txhawm rau txhim kho kev nkag siab ntawm lub hauv paus physics, tshwj xeeb tshaj yog qhov tsis sib xws hauv teeb meem thiab antimatter post-Big Bang. Txawm li cas los xij, kev sib tw tseem nyob. Kev thauj cov antiprotons yuav xav tau kev hloov kho dua tshiab, suav nrog cov tshuab nqus tsev zoo dua thiab cov khoom siv hluav taws xob kom ntev dua. Pab neeg no tab tom tshawb xyuas onboard generators kom ncua sij hawm ua haujlwm thaum thauj.
CERN npaj kev sim ntxiv nrog cov tshuaj tiv thaiv kab mob los ntawm xyoo tom ntej, tsom mus rau European-scale faib. Qhov no tuaj yeem hloov pauv kev tshawb fawb antimatter, tso cai rau ntau lub chaw soj nstuam sib koom ua ke ntawm kev sim ua tsis tau dhau los. Qhov kev ua tiav no qhia txog qhov muaj peev xwm loj tuaj hauv particle physics, thawb cov ciam teb ntawm qhov peb tuaj yeem tshawb nrog cov cuab yeej nyuam qhuav xav txog ib xyoo caum dhau los.
