Abstract
The Telescope Array Low-energy Extension (TALE) experiment is a project that extends the Telescope Array (TA) experiment to observe cosmic rays with energies down to 10<sup>16.5</sup> using 10 fluorescence detectors (FDs) and 80 surface detectors (SDs). The TALE-infill SD array, consisting of 50 SDs arranged in a grid pattern with 100-meter spacing, has been installed to extend observations to lower energies, covering the PeV energy region. The extension as TALE-infill enables precise measurements of the energy spectrum, mass composition, and arrival direction anisotropy of cosmic rays around the knee, with the aim of investigating the origin of cosmic rays and the physical mechanisms responsible for the knee feature. In this paper, we report on the observational status of the TALE-infill array, using the first data from November 2023 to Jun 2024.
