Description
The possibility for a new type of neutrino detector, a “hybrid Cherenkov-scintillation detector,” which observes and discriminates Cherenkov light from scintillation light, has become a reality with a myriad of new technological approaches. One of these approaches, the “dichroicon’”, is a Winston-style light concentrator made from dichroic mirrors which sort photons by wavelength, separating the long-wavelength photons from broadband Cherenkov light from the short-wavelength, narrow-band scintillation light. Dichroicons are also useful in large detectors where dispersion of the light smears out the timing, and allows for excellent particle ID by distinguishing events that create Cherenkov light from those that do not. This poster will describe the dichroicon and characterize its performance with data taken with the CHESS detector, a benchtop scale particle detector located at Berkeley Lab. We will also show simulation results illustrating the impact of dichroicons on event reconstruction in the multi-tonne scale Eos demonstrator, as well as the envisioned 50 tonne-scale Theia detector.
