Scintillator sensors (IMAGE) University of Tokyo Caption These are the sensors used to detect the weakly interacting muon particles. Each scintillator sensor is extremely dense to maximize the chances that a muon will interact with it. Arranged in a grid, the sensors can form a crude image of whatever the muons passed through to reach the sensor.
