ABSTRACT

The research detailed in this paper focuses on an extensive simulation of the HADAR experiment's detection capabilities concerning iron cores and protons. Leveraging a sophisticated software package built on the CORSIKA simulation program, the study meticulously examined the distribution characteristics of secondary particles emitted by iron cores and protons. Discrimination between these primary cosmic rays was accomplished through the utilization of Hillas parameters and MRSW (Modified Hillas parameters - Mean Reduced Scaled Width) parameters. Additionally, a quantitative assessment was introduced in the form of the Q-factor to gauge the effectiveness of both discrimination methods. The obtained results showcase the HADAR experiment's remarkable proficiency in not only detecting but also distinguishing between iron cores and protons. Notably, the MRSW method emerged as highly effective, demonstrating significantly superior discrimination capabilities compared to the Hillas parameters. This advancement is pivotal for the HADAR experiment, providing researchers with a more robust and accurate tool for characterizing cosmic ray events. The successful discrimination achieved in this study contributes valuable insights to the broader field of astroparticle physics. The refined capabilities of the HADAR experiment open new avenues for investigating the intricate properties of cosmic rays, thereby advancing our understanding of high-energy astrophysical phenomena. These findings, presented in this paper, lay the groundwork for future research endeavors and underscore the HADAR experiment's significance in unraveling the mysteries of the cosmos.
