Abstract

We report on the cosmic ray mass composition measured by the Telescope Array Low-energy Extension (TALE) hybrid detector. The TALE detector began operations in 2017 with 10 high-elevation fluorescence telescopes and a surface detector (SD) array of 80 scintillation counters, including 40 with 400 m spacing and 40 with 600 m spacing. In 2023, we constructed a new array made up of 50 SDs with a spacing of 100 m to lower the energy threshold of hybrid mode down to PeV range for the investigation of the cosmic ray mass composition around knee structure in the spectrum. Here we will present an estimate of the performance of the hybrid mode which is a combination of the new SD array and TALE-FD using a Monte Carlo simulation, and report the first preliminary results of the mass composition measurement using the new hybrid detector.
