- ПубликацияТолько метаданныеStudy of EAS Registered by the PRISMA-32 Array and the Cherenkov Water Calorimeter NEVOD(2019) Gromushkin, D. M.; Bogdanov, F. A.; Bouchama, L.; Bulan, A. V.; Izhbulyakova, Z. T.; Khokhlov, S. S.; Stenkin, Y. V.; Yurin, K. O.; Громушкин, Дмитрий Михайлович; Хохлов, Семен Сергеевич; Стенькин, Юрий Васильевич© 2019, Pleiades Publishing, Ltd.Two installations that allow to detect the EAS hadron component in a continuous mode, the Cherenkov water calorimeter (CWC) NEVOD and PRISMA-32 are operated in MEPhI. The comparison of the characteristics of EAS simultaneously registered by CWC NEVOD and PRISMA-32 are presented. Groups of events with different positions of the shower axis are considered.
- 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.
- ПубликацияТолько метаданныеExpected Spectra of Muon-Induced Cascades in IceCube(2019) Khokhlov, S. S.; Bogdanov, A. G.; Kokoulin, R. P.; Petrukhin, A. A.; Sozinov, E. S.; Yurina, E. A.; Хохлов, Семен Сергеевич; Богданов, Алексей Георгиевич; Кокоулин, Ростислав Павлович; Петрухин, Анатолий Афанасьевич; Юрина, Екатерина Александровна© 2019, Pleiades Publishing, Ltd.The neutrino telescope IceCube is capable to reconstruct the energy spectrum of muons in very high energy region by means of measurements of muon-induced cascades. To compare with experimental data, the expected spectra of cascades were theoretically estimated. Calculations were performed for two variants of muon spectrum on the ice surface: a simple power-law energy spectrum with a differential slope index −3.7, and a composite spectrum combined of two power spectra with differential indexes −3.7 and −2.7. The differential spectra of cascades for different zenith angles and integral cascade spectra calculated for two variants of muon spectra are discussed.
- 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 метаданныеInvestigation of the Energy Loss of Muon Bundles in the Cherenkov Water Calorimeter(2019) Mannocchi, G.; Trinchero, G.; Yurina, E. A.; Barbashina, N. S.; Bogdanov, A. G.; Khokhlov, S. S.; Kindin, V. V.; Kokoulin, R. P.; Kompaniets, K. G.; Petrukhin, A. A.; Shutenko, V. V.; Yashin, I. I.; Юрина, Екатерина Александровна; Барбашина, Наталья Сергеевна; Богданов, Алексей Георгиевич; Хохлов, Семен Сергеевич; Киндин, Виктор Владимирович; Кокоулин, Ростислав Павлович; Компаниец, Константин Георгиевич; Петрухин, Анатолий Афанасьевич; Шутенко, Виктор Викторович; Яшин, Игорь Иванович© 2019, Pleiades Publishing, Ltd.Investigations of the energy loss of muon bundles are being conducted at the Experimental complex NEVOD. Such investigations are directed to detailed study of “muon puzzle” (the excess of multi-muon events observed in several cosmic ray experiments at ultra-high energies). Results of measurements of the muon bundle energy deposit during a long period of observations in primary cosmic ray energy range 10–1000 PeV have been obtained and have been compared with simulations performed on the basis of the CORSIKA code.
