Description
IceCube is composed of the surface array IceTop and the volume detector
InIce/DeepCore. This offers unique opportunities for cosmic-ray physics.
One major objective is the measurement of cosmic-ray composition around
and above the knee by correlating the electromagnetic content of air
showers to the high-energy muon yield.
Presented are first results from the surface array and
from analyses using cosmic-ray muons in the in-ice detector.
Cosmic ray primary spectrum and composition were measured from the knee to
the 100 PeV region using combined surface and deep detector data.
Independently, the InIce array alone can be used to constrain primary flux
models and investigate the behavior of the proton flux around the knee.
Using high-energy bremsstrahlung cascades along muon tracks, the cosmic
ray-induced muon energy spectrum can be measured up to hundreds of TeV.
