Cosmic-Ray energy spectrum measurements with IceTop

IceTop, the surface ice-Cherenkov array of the IceCube Neutrino Observatory, detects extensive air showers generated from the interaction of the cosmic rays with the atmosphere. It measures cosmic rays in the PeV-EeV energy range, targeting the transition region between galactic and extragalactic cosmic-ray origins, including spectral features such as the knee and the second knee. A novel two-component LDF method is used for event reconstruction, providing an energy estimator along with mass-dependent parameters. An unfolding procedure is then employed to derive the all-particle energy spectrum from the energy estimator parameter. The details of the analysis will be presented in the conference.
