Monitoring radiation background in the near-surface atmosphere and gamma rays, geoacoustic emission, temperature a borehole at 40 m depth, as well Doppler sounding on low-inclined radio pass, proceeded Tien Shan mountain station (3340 a.s.l.) northern with common goal of searching for seismogenic effects preceding earthquakes. The flux rays varied negligibly between days, it was not influenced by precipitation. Characteristic bay-like drops ray were found (2–8) days before M5.0–M6.2 In an...
Energetic radiation during thunderstorms is studied. The possibility to identify the high-energy lightning emission in 10 s monitoring mode demonstrated. Simultaneous measurements of gamma-ray emission, electrons, and neutron triggering are fulfilled. Energy spectra gamma electrons obtained. intensity both rays discharge prevail background by 1.5 2 orders magnitude.
During the catastrophic M7.8 earthquake in Turkey on 6 February 2023, anomalous effects were revealed ionosphere associated with various propagation mechanisms of seismogenic disturbance from lithosphere up to height ionosphere. Seventeen minutes after main shock, a co-seismic was detected by Doppler ionosonde an inclined, 3010 km long, two-hop radio path “Kuwait—Institute Ionosphere (Almaty)”. An appearance acoustic waves at 232 fixed 568 s arrival surface Rayleigh wave sub-ionospheric...
After the explosive eruption of Hunga Tonga volcano on 15 January 2022, disturbances were observed at a distance about 12,000 km in Northern Tien Shan and regarded variations atmospheric pressure, telluric current, Doppler frequency shift ionospheric signal. At 16:00:55 UTC, pulse pressure was detected there, with peak amplitude 1.3 hPa propagation speed 0.3056 km/s, equal to velocity Lamb waves. In shift, two types registered 3212 2969 long inclined radio paths, one which arose as response...
The article describes in detail the equipment and method for measuring Doppler frequency shift (DFS) on an inclined radio path, based principle of phase-locked loop using SDR receiver investigation seismogenic man-made disturbances ionosphere. During two M7.8 earthquakes Nepal (25 April 2015) Turkey (6 February 2023), a ionosonde detected co-seismic pre-seismic effects ionosphere, appearances which are connected with various propagation mechanisms disturbance from lithosphere up to One day...
The events of multiple neutron production under a 2000 g/cm2 thick rock absorber were studied at the Tien Shan mountain cosmic ray station, an altitude 3340 m above sea level. From comparison experimental and Geant4 simulated multiplicity spectra it follows that great bulk these can be explained by interaction muons with internal material detector. In synchronous operation underground monitor shower detector system was found characteristics muonic component extensive air showers which is...
A search for the possible precursors of an earthquake and its effect on data series diverse geophysical parameters has been made in mountain Northern Tien Shan. The complex installation included NM64 type neutron supermonitor, detectors environmental low-energy neutrons, scintillation gamma-detector, sensor local electric field, a seismograph, weather-station. specialized filtration methodic was elaborated with enhanced sensitivity to transient signals seismic origin. On eve of, after 5.4...
We present a description of the new complex installation for study extensive air showers which was created at Tien Shan mountain cosmic ray station, as well results first measurements made there in 2015–2016. also on high-energy radiation observed during thunderstorm.
We present the outlines of a new microcontroller based data acquisition system which is aimed for reliable operation in typical cosmic ray particle registration experiment. The supports connection up to 16 input signals and ensures following functionality: (1) stable monitoring intensity digital pulse signal, or digitization continuous potential level with low time resolution (typically, about 1 s–100 s); (2) uninterruptable high-resolution (up 5–10 μs) series signal intensity; (3)...

A special system of acoustic detectors was created to search for possible correlations between wide air showers and the signal elastic oscillations from depths earth's crust. They are intended joint synchronous work with storm installation.
The complex EAS installation of the Tien Shan mountain cosmic ray station which is situated at a height 3340 m above sea level includes scintillation and Cherenkov detectors charged shower particles, an ionization calorimeter set neutron for registering hadronic component shower, number underground penetrative component. Now it intended to expand this with promising method detecting radio-emission generated by particles developing shower. facility detection consists three crossed dipole...
