(Irvine-Michigan-Brookhaven detector)
(1980s neutrino detector)

IMB (for Irvine-Michigan-Brookhaven detector) was a neutrino detector located in a mine in Ohio operating 1981 through 1991, a Cherenkov detector consisting of a tank of pure water surrounded by photomultiplier tubes. Among the detectors accomplishments was detection of a neutrino burst coincident with the EMR of SN 1987A reaching Earth. Also, a one-year experiment checked for proton decay within the water tank and the non-detection translates to a half-life on the order of 1031 years or more.
