All-Particle Cosmic Ray Energy Spectrum Measured with 26 IceTop Stations
We report on a measurement of the cosmic ray energy spectrum with the IceTop air shower array, the surface component of the IceCube Neutrino Observatory at the South Pole. The data used in this analysis were taken between June and October, 2007, with 26 surface stations operational at that time, cor...
