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),本來計劃興建一座大型實驗室用作研究質(zhì)子衰變,這實驗裝置稱為神網(wǎng)號,后來于1984年在美國協(xié)助下,它被改建為有史以來第二個探測太陽中微子的實驗室神網(wǎng)2號。
