DESCRIPTION:Speakers: Liliya Savushkina (National Research Nuclear Univers
 ity MEPhI)\nAssociated with thunderstorm activity gamma-ray bursts (TGF - 
 Terrestrial Gamma-Flash) were discovered in 1994\, by the BATSE instrument
  on board the satellite (cosmic gamma-ray observatory Compton\, NASA). As 
 expected one of the main mechanisms of their generation is bremsstrahlung 
 emission of relativistic electrons\, accelerated by atmospheric electric f
 ield above thunderclouds.  This work is devoted to investigation of the in
 terrelation between TGFs and of high-energy electron bursts\, which have b
 een registered into near-Earth space below the radiation belt. The databas
 e of high-energy electron bursts with energies from 3 to 30 MeV obtained i
 n ARINA and VSPLESK satellite experiments and the database of TGFs registe
 red by RHESSI satellite (with energies up to 17 MeV) were used in this wor
 k. As it was shown earlier the most of electron bursts (70-80%) have the t
 hunderstorm origin. Most of these bursts are associated with precipitation
 s of the electrons from the radiation belts caused by electromagnetic dist
 urbance generated by the lightning discharges. But some bursts could have 
 another origin\, for example\, associated with acceleration-runaway mechan
 ism (Gurevich’s mechanism). In this case\, the electron bursts must be a
 ccompanied with flashes of bremsstrahlung. The database of TGFs and the da
 ta of the high-energy electron bursts were analyzed. The results of the an
 alysis are presented at this work.\n\nhttps://indico.particle.mephi.ru/eve
