Energy Spectrum Measured by the Telescope Array Experiment<sup></sup>

ORAL

Abstract

Telescope Array (TA) is the largest cosmic ray detector in the Northern hemisphere measuring cosmic rays of energies from 3 PeV to 100 EeV and higher. Combined TA energy spectrum consists of two parts: spectrum measured by the main TA surface detector array and the spectrum measured by the TA low energy extension detector (TALE). We present a combined TA and TALE spectrum, compare the result with other experiments, and discuss anisotropies seen in the TA spectrum at the highest energies.
