Results on the spectrum and composition of cosmic rays from the IceTop air shower array of the IceCube Observatory
Univ. of Delaware, USA
a e-mail: tilav@udel.edu
We report on measurements of the energy spectrum and mass composition of cosmic rays above 1 PeV with the data taken during the construction phase of the IceTop and IceCube detectors. We discuss our current systematics and observation of a structure in the energy spectrum above 20 PeV where the mass composition gets heavier than iron nuclei.
