Abstract

The TALE infill experiment is a further extension of TA-TALE detectors to observe low-energy cosmic rays down to the PeV region. TALE infill utilizes the existing TALE-FD detectors, and newly developed "infill" surface detectors with 100 m and 200 m spacing. The new detectors will be deployed at the TALE site in October-November 2022. We present the design and performance of the TALE infill array in the hybrid mode, in terms of the resolutions and biases of arrival direction, energy, and X_max.
