💠 Water Cherenkov Detector: Threshold, Cone Angle, Photon Yield and Light Ring (2D)

Side view of a water tank with a charged particle crossing it, with the blue cone of Cherenkov light and the ring of light that lands on the end cap. Choose the particle, its energy, the refractive index of the medium, the tank size and the sensor coverage, and see the threshold, the cone angle, the number of photons and the expected sensor hits. The threshold energy, the cone from a wavelet construction, the Frank-Tamm photon yield and the ring geometry are checked with four in-page numerical checks.
