A screenshot of a data visualization of a single event captured by super-kamiokande. The detectors cover the full cylindrical surface of the device, and there are two shells of detectors, the inner shell, and the more sparse outer shell. The detectors of the inner shell are plotted in the middle of the picture, and the outer shell smaller in one corner. Each of the roughly 10000 detectors is colored by incident photon energy, painting a picture of a clipped cone.
