   Horn
   Horn is an organic substance made mostly of the fibrous protein called keratin (our nails, hair, bull's horns, feather quills, and horse hoofs are also made of keratin). Some dinosaurs, like Triceratops , had bone-like horns that may have been covered by a layer of keratin (horn) when they were alive. Since keratin does not fossilize well, we do not know if horn covered the bone and if so, how much it was.

    Horn
    A magnetic focusing device used to produce a more intense beam of neutrinos. Charged mesons from the target are focused by these horn shaped pulsed current sheets before they decay into neutrinos and muons, resulting in a more intense neutrino beam. Unlike a standard magnet focusing system, the horns can efficiently focus the meson beam over a wide momentum range.
