Description

ENDA-INR is a sea level prototype of the running now at high altitude in China ENDA (Electron-Neutron Detector array), being a part of the LHAASO experiment. The main task of the ENDA is measuring of primary cosmic ray energy spectrum using hadronic EAS component. The latter is a principal point because only hadrons form the EAS “skeleton” which defined all its properties at observation level. Preliminary experimental results obtained after 3 years of measurements are presented and analyzed.
