“…Experimental data taken at high altitudes show that the hadron distribution at EAS core follows an exponential behavior [53]. The hadron interaction and thermal neutron production have been studied using a GEANT4 based simulation package [54]. The results of the simulation show that the lateral distribution of these thermal neutrons can be conveniently described by a two exponential functional form.…”

We report on a measurement of thermal neutrons, generated by the hadronic component of extensive air showers (EAS), by means of a small array of EN-detectors developed for the PRISMA project (PRImary Spectrum Measurement Array), novel devices based on a compound alloy of ZnS(Ag) and 6 LiF. This array has been operated within the ARGO-YBJ experiment at the high altitude Cosmic Ray Observatory in Yangbajing (Tibet, 4300 m a.s.l.). Due to the tight correlation between the air shower hadrons and thermal neutrons, this technique can be envisaged as a simple way to estimate the number of high energy hadrons in EAS. Coincident events generated by primary cosmic rays of energies greater than 100 TeV have been selected and analyzed. The EN-detectors have been used to record simultaneously thermal neutrons and the air shower electromagnetic component. The density distributions of both components and the total number of thermal neutrons have been measured. The correlation of these data with the measurements carried out by ARGO-YBJ confirms the excellent performance of the EN-detector.2

“…Thermal neutrons are detected with the scintillation detectors during 20 ms after the EAS front arrival. The first results on EAS neutrons (temporal distribution of EAS neutrons, relationship between electron and neutron components, EAS spectrum in terms of the number of neutrons and others) obtained at the PRISMA-32 (MEPhI, Moscow) has demonstrated the potential of such research method [3][4][5][6].…”

It is aimed at studying of primary cosmic rays in the "knee" region of energy spectrum and detects neutrons produced in interactions of EAS particles with nuclei of atmosphere or matter. The array consists of 72 detectors based on the scintillator with natural boron. Scintillator represents a silicon plate with the granules of ZnS(Ag) and B 2 O 3 mixture. The area of the detector is 0.36 sq. m. Detectors are located on two roofs of the MEPhI laboratory buildings and are combined into clusters of 12 detectors. The structure and the main elements of the URAN array are described.

“…It allows us to calculate neutron production by EAS hadrons and the neutron thermalization process. The following results were obtained due to the simulations: energy deposit in the en-detector as a function of energy of EAS particles, dependence of neutron multiplicity on EAS hadrons energy and lateral distribution of recorded neutrons around the hadron trajectory [7]. The CORSIKAbased Monte-Carlo simulation uses dependences obtained with GEANT4 to simulate our experiment.…”

Study of the EAS size spectrum in thermal neutrons measured by the PRISMA-YBJ array

Abstract. An Extensive Air Shower array of a novel type has been constructed in Tibet at an altitude of 4300 m above sea level. It consists of specially designed scintillator en-detectors capable of measuring two main EAS components: hadrons (n) and electrons (e). Results of the experiment are presented. It is demonstrated that the EAS integral distribution in the number of thermal neutrons can be well fitted by a single power law function. Comparison with detailed Monte-Carlo simulations using CORSIKA6.9 and GEANT4.10 codes are also shown.
