Abstract

The Horizon-T detector system was designed to study temporal and spatial structure of the EAS disk from the events with primary particle energy starting from 1016 eV and a wide range of zenith angles. Currently, the main aim of the detector is the detailed structure of the multi-modal events. Between 2017 to 2019 approximately 200 thousand events are recorded from 7848 hours of the physics runs and the analysis is ongoing. The published preliminary analysis for a smaller data subset indicate that the bimodal EAS do not fit the simulation for electron-hadron showers. Thus, the current analysis methods should be adapted for the multimodal events. Additionally, the detector upgrades to study the properties of the multi-modal events are planned, such as the "age" and the energy of particles composing each sub-shower resulting in additional peaks in detectors is being considered.
