Kamioka , situated 300 km west of tokyo of japan , was originally planned to construct a laboratory for the purpose of studying proton decay . the detector was called kamiokande kamioka nucleaon decay experiement . it was ultimately turned into the second solar neutrino detector in history with the assistance of usa in 1984 and was renamed kamiokande ii 座落于日本首都東京以西300公里的神網(wǎng),本來(lái)計(jì)劃興建一座大型實(shí)驗(yàn)室用作研究質(zhì)子衰變,這實(shí)驗(yàn)裝置稱為神網(wǎng)號(hào),后來(lái)于1984年在美國(guó)協(xié)助下,它被改建為有史以來(lái)第二個(gè)探測(cè)太陽(yáng)中微子的實(shí)驗(yàn)室神網(wǎng)2號(hào)。
