The Telescope Array experiment: status and prospects

Telescope Array (TA) is a hybrid detector of a surface detector array andfluorescence telescopes. This hybrid detector will measure the energy spectrum, anisotropy and composition of ultra-high energy cosmic rays (UHECRs) to identify their origin. The almost construction of the detector has been completed in May 2007, and the detector is running under test and adjustments. The ¯rst hybrid observation with the full con¯guration is planned in beginning of 2008. In this paper the status and prospects of TA detector is described
