The dependences of the energy deposit of muon bundles on the zenith angle and the local muon density are obtained for primary energies of 10–1000 PeV. The results from comparing the data to simulations performed with the CORSIKA program are presented.

Estimates of the average energy of muons in the bundles are obtained in the 10 to 1000 PeV range of primary particle energies and compared to values calculated under different assumptions about the composition of cosmic radiation and models of hadronic interactions. An excess of experimental values of the average muon energy relative to calculations is found for high local densities corresponding to primary particle energies above 100 PeV.

I.; Kindin, V. V.; Kokoulin, R. P.; Kompaniets, K. G.; Okuneva, E. A.; Petrukhin, A. A.; Yashin, I. I.; Киндин, Виктор ВладимировичThe concept of the TAIGA experiment is to combine wide-angle timing and imaging Cherenkov telescopes as well as electron and muon detectors. The TAIGA facility aims at gamma-ray astrophysics at energies from a few TeV to several PeV and cosmic-ray physics from 100 TeV to several EeV but also pursues searches for astrophysical nanosecond transients, axion-like particles, Lorentz invariance violation and other unexpected manifestations of New Physics. TAIGA-1, a hybrid detector complex with an area of 1 km2, operating since 2021 in the Tunka valley, 50 km to the West from the southernmost tip of lake Baikal, and the plans for its upgrade are presented.
- ПубликацияТолько метаданныеCherenkov EAS arrays in the Tunka astrophysical center: From Tunka-133 to the TAIGA gamma and cosmic ray hybrid detector(2020) Kuzmichev, L.; Bezyazeekov, P.; Borodin, A.; Bruckner, M.; Astapov, I.; Kindin, V.; Kokoulin, R.; Kompaniets, K.; Petrukhin, A.; Yashin, I.; Астапов, Иван Иванович; Киндин, Виктор Владимирович; Кокоулин, Ростислав Павлович; Компаниец, Константин Георгиевич; Петрухин, Анатолий Афанасьевич; Яшин, Игорь Иванович© 2019 Elsevier B.V. One of the most informative methods of cosmic ray studies is the detection of Cherenkov light from extensive air showers (EAS). The primary energy reconstruction is possible by using the Earth's atmosphere as a huge calorimeter. The EAS Cherenkov light array Tunka-133, with ∼3 km2 geometrical area, is taking data since 2009. Tunka-133 is located in the Tunka Astrophysical Center at ∼50 km west of Lake Baikal. This array allows us to perform a detailed study of the energy spectrum and the mass composition in the energy range from 6⋅1015eV to 1018eV. Most of the ongoing efforts are focused on the construction of the first stage of the detector TAIGA (Tunka Advanced Instrument for cosmic ray physics and Gamma Astronomy). The latter is designed for the study of gamma rays and charged cosmic rays in the energy range of 1013eV–1018eV. The TAIGA prototype will consist of ∼100 wide angle timing Cherenkov stations (TAIGA-HiSCORE) and three IACTs deployed over an area of ∼1 km2. The installation of the array is planned to be finished in 2019 while the data-taking can start already during the commissioning phase. The joint reconstruction of energy, direction, and core position of the imaging and non-imaging detectors will allow us to increase the distance between the IACTs up to 800 m, therefore providing a low-cost, highly sensitive detector. The relatively low cost together with the high sensitivity for energies ≥30–50 TeV make this pioneering technique very attractive for exploring galactic PeVatrons and cosmic rays. In addition to the Cherenkov light detectors we intend to deploy surface and underground muon detectors over an area of 1 km2 with a total area of about 1000 m2. The results of the first season of coincident operation of the first ∼4 m diameter IACT with an aperture of ∼10°with 30 stations of TAIGA-HiSCORE will be presented.

- 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 метаданныеOptimization of electromagnetic and hadronic extensive air shower identification using the muon detectors of the TAIGA experiment(2020) Bezyazeekov, P.; Boreyko, V.; Borodin, A.; Brueckner, M.; Astapov, I.; Kindin, V.; Kokoulin, R.; Kompaniets, K.; Petrukhin, A.; Yashin, I.; Астапов, Иван Иванович; Киндин, Виктор Владимирович; Кокоулин, Ростислав Павлович; Компаниец, Константин Георгиевич; Петрухин, Анатолий Афанасьевич; Яшин, Игорь Иванович© 2018 Elsevier B.V. The TAIGA experiment in the Tunka valley near Lake Baikal is planning an extension with new TAIGA-Muon scintillation detector stations. The main purpose of TAIGA is gamma-ray astronomy in the TeV to PeV energy range and cosmic ray physics. The purpose of the Taiga-Muon detectors is to measure the muon component of air showers for improving cosmic ray composition measurements as well as gamma–hadron separation above 100 TeV. Monte Carlo simulations of the experiment are done with the software packages CORSIKA and GEANT4. Extensive air showers of primary particles in the energy range 100–3000 TeV are created with CORSIKA. The trigger efficiency is calculated and used for optimization. The suppression factor of hadronic showers versus electromagnetic showers is studied, leading to an optimum depth of soil absorber (2 m), at the lowest energy range. Data on the identification efficiency for primary gamma-quanta and proton events are presented as well as the suppression factor.
- ПубликацияТолько метаданныеSearch for Astrophysical Nanosecond Optical Transients with TAIGA-HiSCORE Array(2021) Panov, A. D.; Astapov, I. I.; Beskin, GM. .; Bezyazeekov, P. A.; Kokoulin, R. P.; Petrukhin, A. A.; Yashin, I. I.; Астапов, Иван Иванович; Кокоулин, Ростислав Павлович; Петрухин, Анатолий Афанасьевич; Яшин, Игорь ИвановичA wide-angle Cerenkov array TAIGA-HiSCORE (FOV similar to 0.6 sr), was originally created as a part of TAIGA installation for high-energy gamma-ray astronomy and cosmic ray physics. Array now consist on nearly 100 optical stations on the area of 1 km(2). Due to high accuracy and stability (similar to 1 ns) of time synchronization of the optical stations the accuracy of EAS arrival direction reconstruction is reached 0.1 degrees. It was proven that the array can also be used to search for nanosecond events of the optical range. The report discusses the method of searching for optical transients using the HiS CORE array and demonstrates its performance on a real example of detecting signals from an artificial Earth satellite. The search for this short flares in the HiSCORE data of the winter season 2018-2019 is carried out. One candidate for double repeater has been detected, but the estimated probability of random simulation of such a transient by background EAS events is not less than 10%, which does not allow us to say that the detected candidate corresponds to a real astrophysical transient. An upper bound on the frequency of optical spikes with flux density of more than 10(-4) erg/s/cm(2) and a duration of more than 5 ns is established as similar to 2 x 10(-3) events/sr/h.
