Query: Measurements of energy spectra of relativistic electrons and gamma-rays
  avalanches developed in the thunderous atmosphere with Aragats Solar Neutron
  Telescope   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 atmosphere. We describe the instrument setup, its
operation condition, software, and hardware triggers. We present energy spectra
of a very large thunderstorm ground enhancement (TGE) event observed on 6
October 2021.
