To improve light yield and energy resolution in large-volume neutrino detectors, light concentrators are often mounted on photomultiplier tubes to increase the detection efficiency of optical photons from scintillation or Cherenkov light induced by charged particles. Previous designs of light concentrators are optimized to attain a wide field view of 90 degree and a high efficiency of above 98%. This improvement could be key to future neutrino experiments, such as Jinping, etc.
