1 Jan 2023 | | Abstract: | Recent results in high-energy atmospheric physics link relativistic runaway
electron avalanches (RREA) accelerated by the electric field in thunderclouds
to atmospheric electricity, such as the unique natural phenomenon of
Terrestrial Gamma-Ray Flashes (TGF). Research shows that the mere existence of
runaway electron avalanches is not sufficient to generate a TGF. In an attempt
to settle this issue, a model of relativistic feedback mechanism was suggested.
In this paper, a way of theoretically investigating the mutual influence of
positron and gamma feedback mechanisms is proposed. The electron avalanche
multiplication factor due to this combined feedback is obtained, followed by a
study of minimal conditions of infinite feedback in a thundercloud. | | Source: | arXiv, 2301.00416 | | Services: | Forum | Review | PDF | Favorites | |
