TAIGA—A hybrid array for high energy gamma-ray astronomy and cosmic-ray physics
(2022) Астапов, Иван Иванович; Яшин, Игорь Иванович; Кокоулин, Ростислав Павлович; Петрухин, Анатолий Афанасьевич; Astapov, I. I.; Kindin, V. V.; Kokoulin, R. P.; Kompaniets, K. G.; Okuneva, E. A.; Petrukhin, A. A.; Yashin, I. I.; Киндин, Виктор Владимирович
The 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.

The Experimental complex NEVOD includes several different setups for studying various components of extensive air showers (EAS) in the energy range from 1010 to 1018eV. The NEVOD-EAS array for detection of the EAS electron–photon component began its data taking in 2018. It is a distributed system of scintillation detectors installed over an area of about 104 m2. A distinctive feature of this array is its cluster organization with different-altitude layout of the detecting elements. The main goal of the NEVOD-EAS array is to obtain an estimation of the primary particle energy for events measured by various detectors of the Experimental complex NEVOD. This paper describes the design, operation principles and data processing of the NEVOD-EAS array. The criteria for the event selection and the accuracy of the EAS parameters reconstruction obtained on the simulated events are discussed. The results of the preliminary analysis of experimental data obtained during a half-year operation are presented.

Data of NEVOD-DECOR experiment on investigations of inclined cosmic ray muon bundles for a long time period (May 2012 – May 2020) are presented. Their comparison with the results of calculations based on simulations of extensive air shower hadron and muon components is carried out. The analysis showed that the observed intensity of muon bundles at primary particle energies of about 1018 eV and higher can be compatible with the expectation only under the assumption of an extremely heavy mass composition of cosmic rays. On the contrary, measurements of the depth of the shower maximum in the atmosphere in the experiments using air fluorescence technique, favour a light mass composition of primary cosmic rays at these energies.

Summator-multiplexor of the block of electronics of the NEVOD-EAS array cluster
(2020) Likiy, O. I ; Шульженко, Иван Андреевич; Компаниец, Константин Георгиевич; Пасюк, Никита Александрович; Shulzhenko, I. A.; Kompaniets, K. G.; Pasyuk, N. A.
The paper is devoted to the development of a new summator-multiplexor (SM) for the block of electronics of the cluster of detector stations (BECDS) of the NEVOD-EAS air-shower array. The new summator-multiplexor is designed to replace the currently used SMs based on CAEN N169 units. The developed basic circuit diagram and the operation principle of the new SM are described. The results of testing of a prototype of the new summator-multiplexor for the BECDS of the NEVOD-EAS array are discussed.
