“…The non-uniform location of the detectors is explained by the existence of a free space in the experimental complex, which contains some other arrays, including Cherenkov water detector (in the center) [4]. Design photo of the en-detector is shown in figure 2.…”

The paper is devoted to the results of the EAS neutron component investigations by means of the PRISMA-32 array. The array consists of 32 en-detectors and enables to record delayed thermal neutrons accompanying showers. For registration of thermal neutrons, the scintillator based on 6 Li isotope as a target is used in the detectors. Some results of the processing of data accumulated over a long period of time are presented: the lateral distribution function of neutrons in EAS and preliminary results on EAS neutron multiplicity spectrum and distribution of showers in e/n ratio.

“…The conversion was performed with two limiting assumptions on primary composition (pure protons and pure iron nuclei), using five different hadron interaction models available in CORSIKA: SIBYLL2.1, QGSJET01, QGSJET-II, EPOS1.61 and EPOS1.99. Thus, for each of the two data samples, 10 estimates of the differential primary energy spectrum were derived [7,10]. In Fig.…”

The Russian-Italian NEVOD-DECOR experiment on measurements of the local muon density spectra at various zenith angles gave the possibility to obtain important information on the primary cosmic ray flux and interaction characteristics in a wide energy range from 10 15 to more than 10 18 eV. At large zenith angles and high muon densities, a considerable excess of muon bundles has been found in comparison with expectation. In this paper, an update of these investigations is presented and some new results obtained by the collaboration are discussed.

“…The most recent experiment, similar to our study is the Decor-Nevod experiment, which has been studying near horizontal muon bundles, containing more than 3 muons and up to around 80 muons. These bundles of muons are believed to originate from cosmic ray primaries with energies above 100 PeV [4]. The Decor-Nevod detector is located nearly at sea level (Moscow,Russia) with dimensions 9 x 9 x 26 m 3 .…”

The HAWC (High Altitude Water Cherenkov) gamma ray observatory is able to observe muons with nearly horizontal trajectories. HAWC is located at an altitude of 4100 meters a.s.l. on the Sierra Negra volcano in Mexico. The HAWC detector is composed of 300 water tanks, each 7.3 m in diameter and 4.5 m tall, densely packed over a physical area of 22,000 m 2. Previous and current experiments have observed high zenith angle (near horizontal) muons at or near sea level. HAWC operates as a hodoscope able to observe multi-TeV muons at zenith angles greater than 75 degrees. This is the first experiment to measure near horizontal muons at high altitude and with large (≥ 10 m) separations for multiple muons. These muons are distinguishable from extensive air showers by observing near horizontal particles propagating with the speed of light. The proximity of Sierra Negra and Pico de Orizaba volcanoes provides an additional measurement of muons with rock overburdens of several km water equivalent. We will present the angular distribution and rate at which HAWC observes these muon events.
