Illustrated schematic of a tau neutrino entering the left canyon wall, producing a tau lepton that decays in the valley and fans into an air shower over the detector array on the right wall
Schematic of neutrino detection at TAMBO. An Earth-skimming tau neutrino undergoes a charged-current interaction within the left canyon face, producing a tau lepton. The tau lepton emerges into the valley and decays, creating an air shower that is detected by TAMBO on the opposite canyon face. Credit: TAMBO collaboration.Download full resolution
Three diagrams comparing a flat-plain detector, sensitive only to down-going or only to up-going tau neutrinos, with a canyon detector sensitive to both
A detector on a flat plain is sensitive only to down-going or up-going tau neutrinos. A canyon detector is sensitive to both. Credit: TAMBO collaboration.Download full resolution
Diagram of a mountain with three neutrino tracks: the electron neutrino is absorbed, the muon neutrino passes through, and only the tau neutrino produces an extensive air shower
All flavours have the same interaction probability, but only the tau lepton efficiently creates a detectable air shower in the valley. Credit: TAMBO collaboration.Download full resolution

Simulation of a tau neutrino event in TAMBO. The neutrino interacts inside the opposite valley face and produces a tau lepton whose decay initiates a particle shower detected by the array. Credit: TAMBO collaboration.Download full resolution
