Description

Experimental complex NEVOD is located in the campus of the National Research Nuclear University MEPhI (Moscow) and is the only one in the world capable of carrying out the basic (particle physics and astrophysics) and applied (solar-terrestrial physics) studies by means of cosmic rays (CR) on the Earth's surface in the entire range of zenith angles (0 to 180 degrees) and in a record energy range of CR primary particles (1 – 10^10 GeV). To provide solution of these tasks and to cover the very wide energy range, there were constructed a number of scientific facilities that have no analogues in the world: - large-volume Cherenkov water calorimeter (CWC) (2000 m^3) with a spatial lattice of quasispherical modules (QSM), which is a good homogeneous calorimeter with a 4π aperture capable of detecting both single muons and cascades in water in Cherenkov light with energies from 30 GeV to 100 TeV; - system of scintillation calibration telescopes (SCT) that allows to calibrate the response of QSMs and detect the electromagnetic and muon components of EAS with energies 10^14-10^16 eV; - vertically deployed around the CWC Russian-Italian coordinate-tracking detector DECOR (total area 70 m^2) with a high spatial and angular resolution for the joint detection with CWD of multi-muon events at large zenith angles up to horizon for the generation of which particles of primary CR with energies in the range 10^15 – 10^18 eV are responsible; - muon hodoscope URAGAN with the total setup area 46 m^2 continuously registering angular variations of muon flux in the range of zenith angles from 0 to 80 degrees, for generation of which the processes modulating CR flux with energies from 1 to 100 GeV in the heliosphere are responsible; - prototype detector for measurements of atmospheric neutrons PRISMA-32 which is represents an array of thermal neutron detectors located around the CWD and is designed to detect the hadron component of EAS with energies of 10^14 – 10^16 eV; - NEVOD-EAS array of scintillation detectors deployed around the water detector over an area of 10^4 m^2 for the detection of EAS with energies of 10^15 – 10^17 eV with a traditional technique. To extend the experimental capabilities up to the Mega-Science level, nowadays new large-scale detectors are being deployed around the EC NEVOD: - detector of atmospheric neutrons URAN, which is a development of PRISMA-32 facility on the area about 10^3 m^2; - large-area vertical coordinate-tracking detector TREK (about 250 m^2) with a spatial resolution about 1 mm which allows to increase the upper limit of accessible for investigation primary energies up to 10^19 eV. The description of experimental capabilities of the complex and first results of simultaneous detection of various EAS components are discussed.
