Abstract

As part of the Large High Altitude Air Shower Observatory (LHAASO) project in China, ENDA-64—an extension of the original electron‒neutron detector array (ENDA) consisting of 16 detectors to 64 detectors—has been put into operation. The new array is intended for studying extensive air showers (EAS’s) at energies above 1 PeV and reconstructing the primary energy spectrum and chemical composition of cosmic rays. A prototype of the ENDA cluster has been fabricated on the territory of the Institute for Nuclear Research of the Russian Academy of Sciences in Moscow (ENDA-INR). The paper describes a program developed for fast simulation of the array response. The results obtained using the developed program, the Geant4 simulation software, and experimental data are compared.
