"Chronotron" timing detectors for EAS studies

Abstract

The extensive air showers (EAS) detector system consisting of timing detection is being built for the reconstruction of the EAS axis direction using chronotron timing information. This system consists of eight scintillator-based individual detectors (100 x 100 x 1 cm) using wavelength shifting fibers for light collection ("Chronotron" installation). The goal of the project is to supplement a complex of EAS installations that is located at the elevation of 3340 m above sea level at the (Tien Shan High-altitude Scientific Station) TSHSS near the city of Almaty, Kazakhstan, with the system of detectors with fast timing. This work presents the current design, the characteristics from the simulation and the performance of the prototype.
