Event no. 266-b

IMB (Irvine, Michigan, Brookline), a collaboration between the University of Michigan, the University of California at Irvine, and the U.S. Department of Energy, was an experiment designed to determine the ultimate stability of matter. Computer display of PMT [photomultiplier tubes] hits from a muon produced by a neutrino interaction in IMB detector. Fish-eye view

Event no. 266-c

IMB (Irvine, Michigan, Brookline), a collaboration between the University of Michigan, the University of California at Irvine, and the U.S. Department of Energy, was an experiment designed to determine the ultimate stability of matter. Computer display of PMT [photomultiplier tubes] hits from a muon produced by a neutrino interaction in IMB detector. Cylinder plot

Event no. 266-d

IMB (Irvine, Michigan, Brookline), a collaboration between the University of Michigan, the University of California at Irvine, and the U.S. Department of Energy, was an experiment designed to determine the ultimate stability of matter. Computer display of PMT [photomultiplier tubes] hits from a muon produced by a neutrino interaction in IMB detector. Sphere plot

Upward muon through IMB detector

IMB (Irvine, Michigan, Brookline), a collaboration between the University of Michigan, the University of California at Irvine, and the U.S. Department of Energy, was an experiment designed to determine the ultimate stability of matter. A high energy muon, created by a neutrino interaction in the earth below the detector, enters the bottom and exits the top. The slashes are the PMT [photomultiplier tubes] hits and the purple line is the estimated path of the muon.

Supernove 1987a before and after explosion

IMB (Irvine, Michigan, Brookline), a collaboration between the University of Michigan, the University of California at Irvine, and the U.S. Department of Energy, was an experiment designed to determine the ultimate stability of matter. The blue giant star Sanduleak in the large magellenic cloud exploded 170,000 years ago giving off a pulse of neutrinos that arrived at earth on 23 February 1987. For a few weeks it was as bright as 100 million suns.

IMB (Irvine, Michigan, Brookline), a collaboration between the University of Michigan, the University of California at Irvine, and the U.S. Department of Energy, was an experiment designed to determine the ultimate stability of matter. PMT [photomultiplier tubes] hits from SN [supernovae] event projected onto sphere.
