Description

In MEPhI, the URAN array, consisting of detectors based on scintillator with natural boron, to study neutron EAS has been created. The array consists of 72 en-detectors, in which the recording material is an inorganic scintillator which represents a silicon plate with an alloy granules of mixture of scintillator ZnS (Ag) and B2O3. Thermal neutrons are recorded due to the isotope 10B (main reaction 10B + n → 7Li + α + 2.792 MeV) whose content in natural boron is about 20%. The area of each detector is 0.36 sq. m. Detectors are located on two roofs of the laboratory buildings and are combined into cluster structures of 12 detectors. The URAN setup is aimed at studying of primary cosmic rays in the “knee” region by means of the detection of neutrons produced as a result of interactions of EAS particles with nuclei of atmosphere or matter near the installation. The structure and the main elements of the installation are describes and the first recorded events are demonstrates.
