Tagging single muons and other long-flying relativistic charged particles by ultra-fast timing in air Cherenkov telescopes [PDF]
, 2006 Atmospheric air Cherenkov telescopes are successfully used for ground-based, very high-energy (VHE) gamma ray astronomy. Triggers from the so-called single muon and other long-flying relativistic charged particle events are an unwanted background for the
