- 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).

The detector represents two planes with total area of 30 m2 placed on the opposite sides of Cherenkov water detector of 2000 m3 volume. Each plane consists of 8 large multiwire drift chambers (4000x508x112 mm3). The key advantages of these chambers are a large effective area (1.85 m2) and a good coordinate and angular resolution with a small number of measuring channels. From the beginning of 2017, CTUDC operates as a part of the experimental complex NEVOD. The detector is designed for measuring of high density muon bundles (up to 10 particles per m2) at zenith angles in the range from 30° to 90°. The results of the CTUDC operation during the last year are given, the first distributions of the events in zenith angle, muon bundle multiplicity and density obtained from the detector data are discussed.

S.; Амельчаков, Михаил Борисович; Воробьев, Владислав Станиславович; Кокоулин, Ростислав Павлович; Хохлов, Семен Сергеевич© 2019 Published under licence by IOP Publishing Ltd. The work is devoted to the study of the anisotropy of the high energy cosmic ray flux by means of muon bundles registered during 2012-2018 with the coordinate-tracking detector DECOR, which is a part of the Unique Scientific Facility Experimental complex NEVOD. We have analyzed data for two event samples corresponding to E > 10 15 eV and E > 10 16 eV energy ranges of primary particles. The method of data processing is described and estimates of the dipole anisotropy parameters (the amplitude and the phase) are presented.
