Ithimba lososayensi lizosebenzisa intuthuko ku-high-energy physics ukuskena i-Great Pyramid of Cheops e-Giza lisebenzisa i-cosmic ray muons.
Abacwaningi bafuna ukubheka bajule kwesinye sezimangaliso eziyisikhombisa zomhlaba futhi benze imephu yesakhiwo sangaphakathi sento. Le phrojekthi ibizwa nge-Explore the Great Pyramid (EGP). Phakathi nomsebenzi, ososayensi bazosebenzisa i-muon tomography. Umehluko phakathi kwe-EGP kanye nephrojekthi yangaphambilini, i-ScanPyramids, ukuthi uhlelo olusha lwe-telescopes ye-muon luzoba namandla izikhathi ezingu-100.
I-EGP izosebenzisa izinzwa ezinkulu kakhulu ezizothuthela ezindaweni ezahlukene ngaphandle kwephiramidi. Imitshina izohlanganiswa ezitsheni zokuthutha ezilawulwa izinga lokushisa ukuze zihambe kalula. Ngayinye izoba ngu-12m ubude, 2.4m ububanzi futhi 2.9m ukuphakama. Sekukonke, iphrojekthi izobandakanya izibonakude ezimbili ze-muon.
Ama-cosmic ray muons adalwa lapho izinhlayiya ezinamandla amakhulu ezaziwa ngokuthi imisebe ye-cosmic ziphahlazeka emkhathini woMhlaba. Imisebe ye-cosmic izingcezu zama-athomu - ama-proton anamandla amakhulu namanuclei e-athomu - ahlala endiza esuka eLangeni aye eMhlabeni futhi ephuma emthaleni. Lapho lezi zinhlayiya zishayisana nomkhathi womhlaba, ukungqubuzana kukhiqiza imifudlana yezinhlayiya zesibili. Ezinye zalezi zinhlayiya ziyi-muons.
Ama-muons awazinzile futhi ayabola kuma-microsecond ambalwa nje (izigidi zesekhondi). Kodwa zihamba ngesivinini esiseduze nejubane lokukhanya. Lokhu kuzivumela ukuthi zingene zijule entweni. Kukhona umthombo ongapheli wama-muons avela emisebeni ye-cosmic ehlala iqhuma uMhlaba. Umsebenzi we-muon tomography ukulinganisa kahle izinhlayiya.
I-Muon tomography isetshenziswa kuzinhlelo zokusebenza ezahlukahlukene, njengokuhlola iziqukathi zokuthutha ukuze kutholwe izinto ezingekho emthethweni. Ukuthuthukiswa kwakamuva kwezobuchwepheshe ku-muon tomography kwandisa amandla ayo futhi kuholele ekusetshenzisweni okusha. Ngokwesibonelo, ososayensi base-Italy bazosebenzisa i-muon tomography ukuze babone ingaphakathi leNtaba iVesuvius, benethemba lokuqonda ukuthi ingase iqhume nini futhi.
Isithombe: Kwesokunxele kunomfanekiso weziqukathi ezakha isibonakude. Ngakwesokudla kunomfanekiso wokuthi isibonakude sizomiswa kanjani endaweni.
