Abstract
The TA Low-energy Extension (TALE) experiment extends the reach of the TA experiment on the low-energy side to below $10^{16}\,$eV.
A primary objective of TALE is to study the transition from galactic to extragalactic cosmic rays.
The TALE detector is a hybrid observatory composed of fluorescence telescopes and a surface detector array of scintillation counters.
The surface detectors are arranged with inter-counter spacing optimized for hybrid energy spectrum measurements in the low-energy region.
We analyzed data collected between November 2018 and May 2023, corresponding to 1,247 hours of operation.
In this presentation, we will show the results of the cosmic ray energy spectrum measurement using the TALE hybrid detector.
This measurement will play an important role in understanding the transition from cosmic rays of galactic origin to those of extragalactic origin.
