A Gamma/Electron Spectrometer with Logarithmic ADC based on LC Tank Ring-Down Oscillation Counting
S. Abovyan, A. Chilingarian, D. Pokhsraryan +3
This paper describes the operating principle, circuit implementation, and mathematical basis of a logarithmic analog-to-digital converter (ADC) that exploits the natural exponentia…
Positron acceleration in thunderstorms
A. Chilingarian, B. Sargsyan
Thunderstorm Ground Enhancements (TGEs) are known manifestations of relativistic runaway electron avalanches (RREAs) developing inside thunderclouds. However, the role of positrons…
High-Energy Atmospheric Radiation: From Thunderstorm Ground Enhancements to Terrestrial Gamma-Ray Flashes
A. Chilingarian, L. Hovhannisyan, B. Sargsyan +1
This work presents a unified conceptual and observational framework that reinterprets these radiation bursts as manifestations of the same runaway processes happening at different…
Extreme thunderstorm ground enhancements registered on Aragats in 2023
A. Chilingarian, B. Sargsyan, T. Karapetyan +4
In 2023, a series of intense Thunderstorm Ground Enhancements (TGEs) were recorded on Mount Aragats in Armenia, with five events exceeding the fair-weather cosmic ray flux by more…
Very unusual operation of the electron accelerator above Aragats mountain in Armenia a day after the earthquake in Turkey and Syria
A. Chilingarian, G. Hovsepyan, D. Aslanyan +2
During the multiyear monitoring of particle fluxes and near-surface electric field (NSEF) on the Aragats research station, no runway relativistic electron avalanches have been obse…
Forbush decrease observed by SEVAN particle detector network on November 4, 2021
A. Chilingarian, G. Hovsepyan, H. Martoyan +11
On November 3-4 2021, an interplanetary coronal mass injection (ICME) hits the magnetosphere, sparking a strong G3-class geomagnetic storm and auroras as far south as California an…
Thunderstorm Ground Enhancements: Multivariate analysis of 12 years of observations
A. Chilingarian, G. Hovsepyan, D. Aslanyan +8
We present a survey of more than half a thousand thunderstorm ground enhancements, fluxes of electrons, and gamma rays associated with thunderstorms registered from 2008 to 2022 at…
The horizontal profile of the atmospheric electric fields as measured during thunderstorms by the network of NaI spectrometers located on the slopes of Mt. Aragats
A. Chilingarian, G. Hovsepyan, T. Karapetyan +3
In the present report, we describe the NaI particle detector network and present the first results of the experiment demonstrating that the particle fluxes from the atmospheric ele…
Multi-messenger observations of thunderstorm-related bursts of cosmic rays
A. Chilingarian, G. Hovsepyan, T. Karapetyan +4
We present the facilities of the Aragats Space Environmental Center in Armenia used during multi-year observations of the thunderstorm ground enhancements (TGEs) and corresponding…
Measurements of energy spectra of relativistic electrons and gamma-rays avalanches developed in the thunderous atmosphere with Aragats Solar Neutron Telescope
A. Chilingarian, G. Hovsepyan, T. Karapetyan +2
Aragats solar neutron telescope (ASNT) is a unique instrument allowing to measure the energy spectra of electrons accelerated and multiplied in the strong electric fields of the at…
