Description
The surface detector (SD) array of the Telescope Array (TA) experiment, covering an area of 700 km$^2$ with 507 plastic scintillators, observes ultra-high-energy cosmic rays (UHECRs). In this presentation, we discuss the evaluation of various systematic uncertainties in the cosmic ray energy spectrum measured by the TA SD array, including those arising from the choice of hadronic interaction models and the mass composition of UHECRs.
