【 摘 要 】

The Telescope Array surface detector stations record the temporal development of the signal from the extensive air shower front which carries information about the type of the primary particle. We develop the method to study the primary mass composition of the ultra-high-energy cosmic rays based on multivariate analysis (MVA). We report the preliminary mass composition results based on the Telescope array 5 years data.
