- 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 метаданныеGalactic cosmic ray anisotropy modelling(2020) Peregoudov, D. V.; Soloviev, A. A.; Yashin, I. I.; Shutenko, V. V.; Яшин, Игорь Иванович; Шутенко, Виктор Викторович© 2020 INFRA-M Academic Publishing House (Nauchno-Izdatelskii Tsentr INFRA-M).We calculate the angular distribution of cosmic rays at a given point of the heliosphere under the assumption that the incoming flux from outer space is isotropic. The static magnetic field is shown to cause no anisotropy provided that the observation point is situated out of the trapped particle area. We consider a coronal ejection model in the form of a static cylinder with an axial homogeneous magnetic field inside. We calculate angular distribution samples in the trapped particle area (inside the cylinder) and show that there is a certain cone of directions with a reduced flux. For the same model with the moving cylinder, the angular distribution samples are calculated for different positions of the observation point outside the cylinder. Anisotropy of order of the ejection to light velocity ratio is shown to arise. The calculated samples are in qualitative agreement with URAGAN muon hodoscope data.

- ПубликацияТолько метаданныеMeasuring the Cherenkov light yield from cosmic ray muon bundles in the water detector(2020) Mannocchi, G.; Saavedra, O.; Trinchero, G.; Kokoulin, R. P.; Barbashina, N. S.; Bogdanov, A. G.; Khokhlov, S. S.; Khomyakov, V. A.; Kindin, V. V.; Kompaniets, K. G.; Petrukhin, A. A.; Shutenko, V. V.; Yashin, I. I.; Yurina, E.

An experiment on the measurements of the Cherenkov light yield from inclined cosmic ray muon bundles in water is being conducted at the Experimental complex NEVOD (MEPhI). The total number of Cherenkov photons is nearly proportional to the muon energy deposit (including secondary particles produced by muons and cascades from them) within the detector volume. Since at muon energies above a hundred GeV the energy loss is almost linearly related to the energy of muons, the average energy loss of the bundles carries information about the mean muon energy in such events. The complex includes the Cherenkov water calorimeter NEVOD with a volume of 2000 m3 and the coordinate-tracking detector DECOR with a total area of 70 m2. DECOR data are used to determine the local muon densities in the bundle events and their arrival directions, while the energy deposits are evaluated from the Cherenkov calorimeter response. The detection of the bundles in a wide range of muon multiplicities and zenith angles gives the opportunity to explore the energy range of primary cosmic ray particles from about 10 PeV to 1000 PeV and even higher in frame of a single experiment. Experimental results on the dependence of the muon bundle energy deposit on the zenith angle and the local muon density are presented and compared with expectations based on simulation of the EAS muon component by means of the CORSIKA code.
- 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.

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 метаданныеLocal Muon Density Spectra at Various Zenith Angles Measured with NEVOD-DECOR(2019) Kokoulin, R. P.; Bogdanov, A. G.; Mannocchi, G.; Petrukhin, A. A.; Shutenko, V. V.; Yashin, I. I.; Yurina, E. A.; Кокоулин, Ростислав Павлович; Богданов, Алексей Георгиевич; Петрухин, Анатолий Афанасьевич; Шутенко, Виктор Викторович; Яшин, Игорь Иванович; Юрина, Екатерина АлександровнаData on cosmic ray muon bundles accumulated at the NEVOD-DECOR complex over the period from May 2012 to December 2018 have been analyzed. Local muon density spectra at various zenith angles have been reconstructed and compared with CORSIKA-based simulations. At large zenith angles and high muon multiplicities corresponding to primary particle energies more than about 3 x 10(17) eV an excess of multi-muon events compared to simulations is clearly seen. Present data are compatible with the expectation for recent LHC-adjusted hadron interaction models only under assumption of extremely heavy (iron group nuclei) primary composition. The assumption of a heavy composition is however in contradiction with other EAS observables, such as maximum depth and its fluctuations.
- ПубликацияТолько метаданныеAnalysis of Variations of the Muon and Hadron Components of Cosmic Rays at Different Phases of the Solar Activity During the 11-Year Solar Cycle(2020) Melnikova, I. A.; Kovylyaeva, A. A.; Mishutina, Y. N.; Shutenko, V. V.; Мишутина, Юлия Николаевна; Шутенко, Виктор Викторович© 2020, Pleiades Publishing, Ltd.Abstract: Variations of secondary cosmic rays on the Earth’s surface depend on the solar activity. To study these variations, neutron monitors and muon detectors are used. Observations of muons and hadrons complement each other in terms of the energies of the primary cosmic rays and their angular distribution. Muons save the direction of the motion of primary particles and make it possible to obtain the angular distribution of cosmic ray modulations using a single setup—as a muon hodoscope. This paper presents a comparison of variations of muon and neutron components of cosmic rays at the Earth surface at different phases of the solar activity in the period from 2008 to 2018. For the comparison, data of two neutron monitors (Moscow and Apatity stations) and the muon hodoscope URAGAN were used.

- 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.

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.
