IMB Collaboration
An 8000-ton water Cerenkov detector, 1570 m of water equivalent underground. The modified detector, IMB-3, began operating in May 86. It had 8-inch phototubes attached to wave-shifting plates. The PMT time resolution was improved from 11 to 8 ns. Studies nucleon decays, including monopole induced, stellar-collapse neutrinos, and high-energy cosmic numu's. Data analysis in progress (May 94).
