Telescope Array Experiment
Telescope Array (TA) is a cosmic ray detector in the Northern hemisphere that measures cosmic rays of energies from 1 PeV to 100 EeV and higher. TA is a hybrid detector that consists of a ground array of scintillation counters, covering 700 km$^2$ on the ground, and overlooked by the three fluorescence detector stations. Sensitivity of TA has been extended by the TA low energy extension (TALE) to 1 PeV using additional fluorescence telescopes with higher elevation viewing angles together with an infill array. In this presentation, we describe the experiment and show the latest TA and TALE energy spectrum and TA mass composition results. TA anisotropy results will be described in detail a separate presentation.
