DESCRIPTION:Speakers: Daria Zemlianskaya ()\nToday\, there are many unsolv
 ed mysteries in the physics of atmospheric lightning discharge. The unexpl
 ained phenomenon of atmospheric electricity is gamma-ray bursts observed s
 ince 1994 by space gamma-ray observatories (for example\, BATSE\, Fermi)\,
  created for observing gamma radiation from astrophysical sources. Mysteri
 ous natural gamma radiation of the earth's atmosphere is called Terrestria
 l Gamma-ray Flushes (TGFs). Long-term observation of TGF made it possible 
 to establish that\, apparently\, this natural phenomenon is based on the a
 cceleration of relativistic electrons in the electric fields of thunderclo
 uds. Actually\, the fundamental phenomenon is the avalanche-like multiplic
 ation of fast electrons in matter. This phenomenon was proposed by Gurevic
 h [1]\, it is called runaway breakdown.\nIf we investigate the propagation
  of relativistic avalanches of runaway electrons at a sufficiently large v
 alue of the electric field in the case of two adjoining parts of the cloud
  with opposite directions of the electric field. In the simulation\, this 
 configuration can be described as a system of two cells with different fie
 ld directions and called the simplest reactor. Under certain conditions of
  the system\, the initiation of feedback is possible. Electrons due to the
  presence of a field in the system will be accelerated\, and when they get
  into the field in the opposite direction\, they will turn. Along the way\
 , they will emit gamma quanta\, on which the field does not act\, thus pla
 ying a key role in the formation of a non-stop process.\nIn this paper\, e
 lectrons were described that exist in the system and\, under the action of
  a field\, can begin to oscillate near the plane of separation of two cell
 s\, thereby maintaining feedback in the system of a simple reactor. This r
 elationship can exist even at small cell sizes and small margins. This mea
 ns that for the explosion criterion in a reactor\, not only the gamma feed
 back is essential\, but also electronic communication\, contributes to the
  development of gamma communication.\nThe purpose of this work was to stud
 y the process of gamma and electron multiplication for the simplest reacto
 r\, by modeling on GEANT4. The studies were carried out for particles with
  an energy of 5 MeV at a height of 10 km from the Earth's surface.\n\nhttp
