The Telescope Array (TA) experiment is designed to observe cosmic-ray-induced air showers at extremely high energies. It is being deployed in a desert of Utah, USA; an array of 3 m2 scintillation counters will be distributed over 760 km^ and 3 sets of air fluorescence telescopes will be placed in the perimeter of the array. It's primary purpose is to make a decisive measurement of the cosmic ray spectrum in the GZK cutoff region. We expect the first data from the TA in the spring of 2007. As its unique features are included 1) hybrid measurement planned down to 1017.5 eV, 2) calibration of fluorescence detection by using artificial air showers generated by an electron linac, 3) interaction model calibration by the LHC.
