Abstract

Telescope Array (TA) is an air shower experiment composed of an array of ground particle detectors and 3 sets of fluorescence telescopes installed in Utah, USA. It aims at drawing a conclusion on the (non-)existence of the GZK cutoff reported controversially by AGASA and HiRes experiments. An anisotropy of the UHECR arrival directions will be studied in the northern hemisphere where the galactic disturbances are small. The plastic scintillator is useful for the determination of the air shower energy independent of the hadronic interaction model and the primary composition. Various calibration methods will be applied for the accurate determination of event energy scale. A total acceptance of the ground array and the telescope will be more than 20 times larger than that of AGASA. An operation of partial detector has started in spring 2007. The status of the experiment is reported and prospects for the physics are given.
