Upward muon through IMB detector [IMB neutrino research project]
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.
