The array for Upstairs Registration of Atmospheric Neutrons (URAN) is now under construction in MEPhI in co-operation with INR RAS. The basic element for the array is en-detector sensitive to both thermal neutron and electromagnetic components. This detector is based on a thin layer of alloyed mixture of inorganic scintillator ZnS(Ag) with B 2 О 3 as a target for neutrons. Main feature of the detector is its sensitivity to hadronic EAS component through secondary neutrons produced by high energy hadrons in the vicinity of the detector. Neutron component is almost not studied, though it is a part of the main EAS component: hadronic one. Some new features of a novel en-detector are described. It is shown that this relatively cheap detector version can have rather good performances.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
