- ПубликацияТолько метаданныеInvesigation of the Local Anisotropy of Cosmic Ray Muon Flux During Coronal Mass Ejections in 2007–2018(2019) Astapov, I. I.; Barbashina, N. S.; Dmitrieva, A. N.; Konovalova, A. Y.; Osetrova, N. V.; Shutenko, V. V.; Yashin, I. I.; Астапов, Иван Иванович; Барбашина, Наталья Сергеевна; Дмитриева, Анна Николаевна; Коновалова, Алена Юрьевна; Шутенко, Виктор Викторович; Яшин, Игорь Иванович© 2019, Pleiades Publishing, Ltd.Coronal mass ejections are among the most powerful disturbances of the interplanetary space. They can influence the state of the near-Earth space, including magnetosphere of the Earth. In addition, such disturbances modulate the flux of cosmic rays and penetrate both the heliosphere and the Earth’s magnetosphere. In order to find an early alert of such events, it is necessary to investigate the flux of particles arriving to the Earth and providing information about events in the heliosphere. The paper presents the results of investigation of the anisotropy of the cosmic ray muon flux by means of the muon hodoscope URAGAN in the period from 2007 to 2018.

- ПубликацияТолько метаданныеNEVOD–DECOR Experiment on the Measurement of the Energy Deposit of Cosmic Ray Muon Bundles(2020) Mannocchi, G.; Trinchero, G.; Yurina, E. A.; Barbashina, N. S.; Bogdanov, A. G.; Kindin, V. V.; Kokoulin, R. P.; Kompaniets, K. G.; Petrukhin, A. A.; Khokhlov, S. S.; Shutenko, V. V.; Yashin, I. I.; Юрина, Екатерина Александровна; Барбашина, Наталья Сергеевна; Богданов, Алексей Георгиевич; Киндин, Виктор Владимирович; Кокоулин, Ростислав Павлович; Компаниец, Константин Георгиевич; Петрухин, Анатолий Афанасьевич; Хохлов, Семен Сергеевич; Шутенко, Виктор Викторович; Яшин, Игорь Иванович© 2020, Pleiades Publishing, Ltd.Abstract: In comparison with calculations, the excess of multimuon events found in many experiments at ultrahigh energies of extensive air showers (EASs) cannot be explained using modern models of hadron interactions. The existence of muon excess is called the muon puzzle. One of the ways to solve this problem is to study the energy characteristics of the EAS muon component. For this purpose, the energy deposit of cosmic ray muon bundles is measured in the NEVOD–DECOR experiment. Registration of muon bundles in a wide range of zenith angles allows one to explore a wide range of energies of the primary particles of cosmic rays (from 10 to 1000 PeV) within a single experiment. The results of measurements of the energy deposit of muon bundles over a long observation period are presented.
- ПубликацияТолько метаданныеReal-Time GSE Mapping of Muon-Flux Directional Variation with the URAGAN Hodoscope(2019) Yashin, I. I.; Astapov, I. I.; Barbashina, N. S.; Dmitrieva, A. N.; Kompaniets, K. G.; Petrukhin, A. A.; Shutenko, V. V.; Яшин, Игорь Иванович; Астапов, Иван Иванович; Барбашина, Наталья Сергеевна; Дмитриева, Анна Николаевна; Компаниец, Константин Георгиевич; Петрухин, Анатолий Афанасьевич; Шутенко, Виктор Викторович© 2019, Allerton Press, Inc.Abstract: Continuous monitoring of the muon flux over wide ranges of zenith and azimuth angles with the URAGAN detector (Moscow, 55.7° N, 37.7° E, 173 m AMSL) allows detection of variations in its intensity and angular distribution. A way of locating domains of anisotropy in the muon angular distribution is described, and they are mapped in matrix form in the GSE coordinate system. The maximum depth (height) of deformation, the zenith and azimuth angles of the center in the local system, and its GSE longitude and latitude are determined for each observed domain. The GSE longitudes of the detected domains of anisotropy are available on the Internet as functions of time and can be used to monitor the heliosphere’s activity.
- ПубликацияТолько метаданныеA Way of Detecting Local Muon-Flux Anisotropies with the Matrix-Form Data of the URAGAN Hodoscope(2019) Dobrovolsky, M. N.; Gvishiani, A. D.; Getmanov, V. G.; Peregoudov, D. V.; Astapov, I. I.; Barbashina, N. S.; Dmitrieva, A. N.; Kovilyaeva, A. A.; Petrukhin, A. A.; Shutenko, V. V.; Yashin, I. I.; Астапов, Иван Иванович; Барбашина, Наталья Сергеевна; Дмитриева, Анна Николаевна; Петрухин, Анатолий Афанасьевич; Шутенко, Виктор Викторович; Яшин, Игорь Иванович© 2019, Allerton Press, Inc.Abstract: A way of detecting local anisotropies of the muon flux using the matrix-form data of the URAGAN hodoscope (MEPhI) is proposed. Confidence intervals for estimating the matrix-data mathematical expectations in observations with reference and sliding data-sampling periods are selected, indicator functions are constructed, and a procedure for space–time filtering is developed. The results are presented from a search for local anisotropy in the muon flux recorded in the matrix-form data of the URAGAN hodoscope.
- ПубликацияТолько метаданныеStudying Powerful Coronal Mass Ejections That Occurred in September 2017, According to Data from the URAGAN Muon Hodoscope(2019) Osetrova, N. V.; Astapov, I. I.; Barbashina, N. S.; Borog, V. V.; Dmitrieva, A. N.; Астапов, Иван Иванович; Барбашина, Наталья Сергеевна; Борог, Владимир Викторович; Дмитриева, Анна Николаевна© 2019, Allerton Press, Inc.Abstract: At the beginning of September 2017, the Sun was characterized by anomalously high solar activity (SA), which was unusual for the region of the minimum of the 11-year cycle. A great many powerful flares of the M- and X-classes were observed; these were accompanied by powerful coronal mass ejections (CMEs). These events caused strong magnetic storms on the Earth (the Kp index was as high as 8; the Dst index was <−140 nT). In this work, the effect these ejections had on the flux of cosmic rays (CRs) is considered using data from the URAGAN muon hodoscope at the Moscow Engineering Physics Institute. The study is based on an analysis of variations in the cosmic ray muon flux. Results are presented from processing flux intensity via flicker-noise spectroscopy in order to identify geoeffective disturbances of the Earth’s magnetosphere. A predictor that precedes by more than one day the emergence in near-Earth space of disturbances related to CME propagation is obtained.

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.
