Duba wurin da ke ƙasa sannan ka amsa tambayar daga baya a cikin harshe ɗaya kamar yadda wurin yake:  Passage: A cikin 1984, Herb Chen na Jami'ar California a Irvine ya fara nuna fa'idodin amfani da ruwa mai nauyi a matsayin mai gano neutrinos na rana. Ba kamar masu ganowa na baya ba, yin amfani da ruwa mai nauyi zai sa mai ganowa ya zama mai saurin amsawa guda biyu, amsawa ɗaya mai saurin amsawa ga duk abubuwan ƙanshin neutrino, ɗayan kuma mai saurin amsawa ga neutrino na lantarki kawai. Don haka, irin wannan na'urar ganowa na iya auna oscillations na neutrino kai tsaye. Wani wuri a Kanada ya kasance mai ban sha'awa saboda Atomic Energy of Canada Limited, wanda ke kula da manyan ɗakunan ruwa mai nauyi don tallafawa tashoshin wutar lantarki na CANDU, ya yarda ya ba da kuɗin da ake buƙata (darajar C $ 330,000,000 a farashin kasuwa) ba tare da tsada ba.Ramin Creighton a Sudbury, daga cikin mafi zurfi a duniya kuma saboda haka ƙananan radiation na baya, an gano shi da sauri a matsayin wuri mai kyau don gwajin Chen da aka ba da shawarar a gina, kuma gudanar da ma'adinai ya yarda ya ba da wurin don ƙarin kuɗi kawai.
