- ПубликацияТолько метаданныеNear-Vertical Local Density Spectra of the EAS Charged Particles in the Energy Range of 1014–1017 eV(2019) Amelchakov, M. B.; Bogdanov, A. G.; Khokhlov, S. S.; Kokoulin, R. P.; Petrukhin, A. A.; Shulzhenko, I. A.; Yashin, I. I.; Амельчаков, Михаил Борисович; Богданов, Алексей Георгиевич; Хохлов, Семен Сергеевич; Кокоулин, Ростислав Павлович; Петрухин, Анатолий Афанасьевич; Шульженко, Иван Андреевич; Яшин, Игорь Иванович© 2019, Pleiades Publishing, Ltd.The results of the long-term measurements of extensive air showers with the calibration telescope system of the Cherenkov water detector are presented for an energy range of 1014–1017 eV. We have used two independent methods for reconstruction of the charged particle local density spectrum: by the multiplicity of the hit counters and by their amplitude responses. By means of Geant4 calculations, we have shown how the structure of the building and the water tank affect the results of the spectrum reconstruction. We obtained two different exponents of charged particles’ local density spectra for CTS top and bottom plane. The results are compared with CORSIKA calculations and data from other setups.
- ПубликацияТолько метаданныеAnisotropy in the Directions of Arrival of Muon Bundles Detected at the NEVOD Experimental Complex(2019) Khohlov, S. S.; Amelchakov, M. B.; Vorobyev, V. S.; Izhbulyakova, Z. T.; Kovylyaeva, A. A.; Хохлов, Семен Сергеевич; Амельчаков, Михаил Борисович; Воробьев, Владислав Станиславович© 2019, Allerton Press, Inc.Abstract: Results are presented from studying the anisotropy of the flux of very high-energy cosmic rays on the basis of muon bundles. Events were recorded in the period 2012–2018 by the DECOR coordinate-tracking detector, part of the unique research setup of the NEVOD experimental complex. The results from analyzing the anisotropy for two samples of events with muon bundles corresponding to different ranges of primary particle energy (E > 1015 eV and E > 1016 eV) are discussed, and estimates are made of dipole anisotropy parameters (amplitude and phase).
- ПубликацияТолько метаданныеMulticomponent Registration of the EAS(2019) Mannocchi, G.; Trinchero, G.; Amelchakov, M. B.; Barbashina, N. S.; Bogdanov, A. G.; Gromushkin, D. M.; Zadeba, E. A.; Kindin, V. V.; Kokoulin, R. P.; Kompaniets, K. G.; Chiavassa, A.; Likiy, O. I.; Petrukhin, A. A.; Stenkin, Y. V.; Khokhlov, S. S.; Shulzhenko, I. A.; Shutenko, V. V.; Yurin, K. O.; Yashin, I.

It includes several facilities for studying the electron–photon, muon, and hadron components of the EAS in the energy range of 1 PeV to 1 EeV. This work presents the first results for two months of the joint operation of five facilities (NEVOD-EAS, CWD, CTS, PRISMA-32, and DECOR). The problems of synchronizing the facilities and selecting joint events are considered. The experimental data of these facilities are analyzed for different components of the EAS in overlapping energy ranges.
- ПубликацияТолько метаданныеReconstruction of Characteristics of Extensive Air Showers Detected with the NEVOD-EAS Array(2019) Likiy, O. I.; Amelchakov, M. B.; Bogdanov, A. G.; Chiavassa, A.; Khokhlov, S. S.; Kokoulin, R. P.; Shulzhenko, I. A.; Амельчаков, Михаил Борисович; Богданов, Алексей Георгиевич; Хохлов, Семен Сергеевич; Кокоулин, Ростислав Павлович; Шульженко, Иван Андреевич© 2019, Pleiades Publishing, Ltd.In 2018, the creation of the central part of the NEVOD-EAS cluster-type array aimed at detection of the electron-photon component of extensive air showers in the energy range from 1015 to 1017 eV was completed. At present, a continuous data taking is being performed at the array. The results of the reconstruction of registered extensive air showers using the methods developed within the framework of the cluster approach to experimental data analysis are presented.
