The importance of electron-electron bremsstrahlung for terrestrial gamma-ray flashes, electron beams and electron-positron beams
Thunderstorms emit terrestrial gamma-ray flashes with photon energies of up to tens of MeV and electron-positron beams that are created by photons with energies above 1.022 MeV. These photons are…
Energy resolved positron and hadron spectrum produced by a negative stepped lightning leader
Gamma-ray flashes with quantum energies up to 40 MeV and beams of electrons and positrons have been detected by satellites above thunderclouds. We here adopt the model of an upward moving negative…
Calculation of beams of positrons, neutrons, and protons associated with terrestrial gamma ray flashes
Positron beams have been observed by the Fermi satellite to be correlated with lightning leaders, and neutron emissions have been attributed to lightning and to laboratory sparks as well. Here we…
Production mechanisms of leptons, photons, and hadrons and their possible feedback close to lightning leaders
TLDR
The feedback mechanism together with the field enhancement by lightning leaders yields particle energies even above 40 MeV measurable at satellite altitudes, because of their high rest mass hadrons are measurable on a longer time scale than leptons and photons.
The structure of ionization showers in air generated by electrons with 1 MeV energy or less
Ionization showers are created in the Earth's atmosphere by cosmic particles or by run-away electrons from pulsed discharges or by the decay of radioactive elements like radon and krypton. These…
A review of electron–nucleus bremsstrahlung cross sections between 1 and 10 MeV
Electron-positron pairs and radioactive nuclei production by irradiation of high-Z target with \gamma-photon flash generated by an ultra-intense laser in the $\lambda^3$ regime
This paper studies the interaction of laser-driven γ-photons and high energy charged particles with high-Z targets through Monte-Carlo simulations. The interacting particles are taken from…
The Emission of Terrestrial Gamma Ray Flashes From Encountering Streamer Coronae Associated to the Breakdown of Lightning Leaders
Terrestrial gamma ray flashes (TGFs) are beams of high‐energy photons associated to lightning. These photons are the bremsstrahlung of energetic electrons whose origin is currently explained by two…
Analyzing x-ray emissions from meter-scale negative discharges in ambient air
When voltage pulses of 1 MV drive meter long air discharges, short and intense bursts of x-rays are measured. Here we develop a model for electron acceleration and subsequent photon generation within…
X-ray diagnostics of ECR ion sources-Techniques, results, and challenges.
The high magnetic confinement provided by the minimum-B structure of electron cyclotron resonance ion sources (ECRIS) hosts a non-equilibrium plasma, composed of cold multi-charged ions and hot…

TLDR
A reformulation of the relativistic bremsstrahlung code of Tseng and Pratt is reported, again utilizing partial-wave and multipole expansions in a screened potential within the independent particle approximation, but differently organizing their summation.
The Elementary Process of Bremsstrahlung
Abstract In this report we review the experimental and theoretical developments concerning the elementary process of electron bremsstrahlung. The term “elementary process” means that not only the…
Erratum: Pair production and bremsstrahlung of charged leptons
Photo pair productions of electrons, muons and heavy leptons and bremsstrahlung of electrons and muons are reviewed. Atomic and nuclear form factors necessary for these calculations are discussed.…
The relativistic feedback discharge model of terrestrial gamma ray flashes
[1] As thunderclouds charge, the large-scale fields may approach the relativistic feedback threshold, above which the production of relativistic runaway electron avalanches becomes self-sustaining…
Terrestrial gamma-ray flashes as powerful particle accelerators.
TLDR
It is determined that the TGF emission above 10 MeV has a significant power-law spectral component reaching energies up to 100 MeV, and these results challenge TGF theoretical models based on runaway electron acceleration.
