Performances of ENDA-INR prototype array

Abstract

Abstract Electron Neutron Detector Array (ENDA) is an ambitious project inside the Large High Altitude Air Shower Observatory (LHAASO) in China, Tibet. ENDA is intended to measure simultaneously electronic and hadronic components of the extensive air showers (EAS) over large area of 104 m2. The array will consist of 400 specially developed electron-neutron detectors based on inorganic ZnS(Ag) + B 2 O 3 scintillator compound. The prototype ENDA cluster of 16 electron-neutron detectors has been build in Moscow in the Institute for Nuclear Research of Russian Academy of Sciences and named ENDA-INR. The main goal of the array is to test techniques of simultaneous measurement of extensive air showers and background variations using pulse shape selection. Details of the array and its techniques are presented.
