Boosted Tau Lepton as a Microscope and Macroscope

Figure 5

An illustration of the proposed underground experiment to catch cosmic tau and muon neutrinos with energy at 10 TeV and above. The 100-meter size cube in the center represents the tracker and calorimeter modules as shown in Figure 4. The dashed lines are for RPC detectors. The surrounding rocks can effectively enhance the target volume on top of the detector’s materials. Two example events are shown in the plot for passing through the detector leaving a long track, and with decay in the cube. The cross points symbol the interactions points where neutrinos turn into lepton. The dot point symbols the place where tau lepton decays.
