E hoʻohana kekahi pūʻulu ʻepekema i nā holomua i ka physics kiʻekiʻe e nānā i ka Pyramid Nui o Cheops ma Giza me ka hoʻohana ʻana i nā muon ray cosmic.
Makemake nā mea noiʻi e nānā hohonu i loko o kekahi o nā mea kupanaha ʻehiku o ka honua a palapala ʻia i ke ʻano o loko o ka mea. Kapa ʻia ka papahana ʻo Explore the Great Pyramid (EGP). I ka wā o ka misionari, e hoʻohana nā ʻepekema i ka muon tomography. ʻO ka ʻokoʻa ma waena o EGP a me ka papahana mua, ScanPyramids, ʻo ia ka ʻōnaehana hou o nā telescopes muon e ʻoi aku ka ikaika o 100 mau manawa.
E hoʻohana ʻo EGP i nā mea ʻike nui loa e neʻe i nā wahi like ʻole ma waho o ka pyramid. E hōʻuluʻulu ʻia nā mea ʻike i nā pahu hoʻouna i mālama ʻia i ka wela no ka lawe maʻalahi. He 12m ka lōʻihi, 2.4m ka laula a me 2.9m ke kiʻekiʻe. Ma ka huina, e komo ana ka papahana i elua telescope muon.
Hoʻokumu ʻia nā cosmic ray muons i ka wā e hāʻule ai nā ʻāpana ikehu kiʻekiʻe i kapa ʻia ʻo cosmic rays i ka lewa o ka Honua. ʻO nā kukuna cosmic nā ʻāpana o nā ʻātoma - nā protons ikaika a me nā nuclei atomic - lele mau mai ka Lā a i ka Honua a ma waho o ke aniani. Ke hui nei kēia mau ʻāpana me ka lewa o ka Honua, hoʻopuka ka hui ʻana i nā kahawai o nā ʻāpana lua. ʻO kekahi o kēia mau ʻāpana he muon.
ʻAʻole paʻa a palaho nā muons i loko o nā microseconds wale nō (millionths o kekona). Akā, neʻe lākou ma kahi wikiwiki kokoke i ka māmā o ka māmā. Hiki iā lākou ke komo hohonu i loko o ka mea. Aia kahi kumu pau ʻole o nā muon mai nā kukuna cosmic e hoʻopā mau ana i ka Honua. ʻO ka hana o ka muon tomography ke ana pono i nā ʻāpana.
Hoʻohana ʻia ʻo Muon tomography i nā ʻano noi like ʻole, e like me ka nānā ʻana i nā pahu hoʻouna no nā mea kūʻē. Hoʻonui ka mana o nā ʻenehana hou i ka muon tomography a alakaʻi i nā noi hou. No ka laʻana, e hoʻohana nā ʻepekema ma Italia i ka muon tomography e kiʻi i ka loko o ka mauna ʻo Vesuvius, me ka manaʻo e maopopo i ka wā e hū hou ai.
Kiʻi: Aia ma ka ʻaoʻao hema he kiʻi kiʻi o nā ipu i hana i ke telescope. Aia ma ka ʻākau he kiʻi no ke ʻano o ka hoʻonohonoho ʻia ʻana o ke telescope.
