EC NEVOD
Experimental complex NEVOD
Operational
The Unique Scientific Facility “Experimental Complex NEVOD” is the only in the world that allows conducting basic (particle physics and astrophysics) and applied (monitoring of the state of the atmosphere and magnetosphere of the Earth and of extra-terrestrial space) research based on the analysis of detected of natural fluxes of the particles at the Earth’s surface over the entire range of zenith angles (from 0 to 180 degrees) and in the record energy range (1 – 1010 GeV).
The Unique Scientific Facility “Experimental Complex NEVOD” is the experimental site ground for the development, testing and calibration of the new nuclear physics equipment and new methods and approaches.

Particle Physics, High and Ultra-high Energy Physics
Key words: high energy physics, cosmic rays, extensive air showers
SCIENTIFIC GOALS
Fundamental goals: the study of characteristics of the primary cosmic ray flux, processes of generation and interaction of known particles, the search for new particles and states of matter in a wide range of energies, including energies 10 times higher than those accessible at the Large Hadron Collider.
Applied goals: the distant monitoring and forecasting of the state of the Earth’s atmosphere and magnetosphere aimed at the early recognition of potentially dangerous magnetospheric and atmospheric phenomena over the territory of about 10,000 square kilometers.
FACILITIES
|
The Unique Scientific Facility “Experimental Complex NEVOD” combines ten different detectors that have no analogues in the world: a Cherenkov water detector (CWD) with a volume of 2000 cubic meters capable to measure the energy deposit of charged particles in a wide dynamic range, the coordinate-tracking detectors DECOR with a total area of 72 square meters with angular (better than 1 degree) and spatial (1 cm) accuracy and TREK with an area 250 square meters with spatial (1 mm) resolution, the muon hodoscopes URAGAN with an area of 46 square meters and ScMH with an area of 23 square meters providing muonographs of the upper hemisphere in real-time mode, a calibration telescope system (CTS) that allows allocation of 1600 different muon trajectories and detection of electromagnetic and muon components of extensive air showers (EAS), a NEVOD-EAS array with an area of 10 000 square meters for measuring charged EAS component, the neutron arrays PRISMA-36, URAN and “Neutron” providing thermal neutrons detection under different conditions (inside the building, underground and on the buildings roofs). |
CHALLENGES
Conducting research in the record energy range of 1010 – 1019 eV, development, testing and calibrating nuclear-physics equipment, as well as training students and postgraduates through their direct participation in real physical experiments.
