Cosmic Ray Composition from the 40-string IceCube/IceTop Detectors
The IceCube Observatory at the South Pole is composed of a deep detector and a surface detector, IceTop, both of which use Cherenkov light to detect charged particles. Cosmic ray air showers contain multiple particle components: in particular, electrons and muons detectable at the surface by IceTop,...
