Abstract: (SISSA)

The TA

\times

4 experiment aims to better understand the origin and nature of ultra-high energy cosmic rays (UHECRs) by expanding the observation area of the Telescope Array (TA) experiment by a factor of 4. This expansion will increase the statistics of UHECR events with energies greater than 10

^{19.5}

eV. The SD, which means the additionally deployed surface detectors (SD) for the TA

\times

4 experiment, has been collecting data since 2019, and the analysis of this data is currently underway. In this presentation, we will report comparisons between the Monte Carlo simulation and the data obtained by the TA

\times

4 SD array and highlight the agreement between the two. We will also report on the UHECR energy spectrum observed by the TA

\times

4 SD array from October 2019 to September 2022.
