DESCRIPTION:Speakers: Fedor Bogdanov ()\nOne of the most important directi
 ons in the research of extensive air showers (EAS) is the study of its had
 ronic component. It is the main component of the EAS\, which forms the cha
 racteristics of the shower. Registration of neutrons produced in interacti
 ons of EAS hadrons with the environment is one of the new methods for stud
 ying EAS hadronic component. The URAN array was created in the Scientific 
 and Educational Center NEVOD (MEPhI) in collaboration with INR RAS. The UR
 AN facility was designed to register neutrons that accompany EAS in the re
 gion of the primary cosmic ray spectrum break (‘knee region’). It incl
 udes 72 detectors based on a thin inorganic scintillator for registration 
 of the charged and neutron components of the EAS. The total area of the fa
 cility is ~ 103 m2\; scintillation detectors are located on the roofs of t
 he laboratory buildings of the Unique Scientific Facility NEVOD. For the c
 orrect interpretation of the experimental data of the URAN\, the response 
 of the URAN facility to the passage of EAS was simulated using the CORSIKA
 7.6900 program and Geant4.10.5 software package. The report presents the r
 esults of studying the parameters of EAS registered by the URAN array in 2
 019. It includes the LDF of charged particles\, the dependence of the numb
 er of neutrons on the parameters of EAS\, the EAS distribution in the numb
 er of neutrons. A comparison of the experimental data with model calculati
 ons is presented.\n\nhttps://indico.particle.mephi.ru/event/35/contributio
