MARIACHI Laboratory. Its inventors hope the MARIACHI apparatus will detect UHECR over much larger areas than previously possible, and that it will also detect ultra-high-energy neutrino flux. The ground array detectors are scintillator arrays that are built and operated by high school students and teachers. MARIACHI MARIACHI, the Mixed Apparatus for Radar Investigation of Cosmic-rays of High Ionization, is an apparatus for the detection of ultra-high-energy cosmic rays (UHECR) via bi-static radar interferometry using VHF transmitters. MARIACHI is also the name of the research project created and directed by Brookhaven National Laboratory (BNL) on Long Island, New York, initially intended to
