Using a NaI(Tl) scintillation detector designed to operate in electrically noisy environments, we observed intense bursts of energetic radiation (≫10 kiloelectron volts) during the dart leader phase of rocket-triggered lightning, just before and possibly at the very start of 31 out of the 37 return strokes measured. The bursts had typical durations of less than 100 microseconds and deposited many tens of megaelectron volts into the detector. These results provide strong evidence that the… Expand
Energetic Radiation Bursts Associated with Lightning
During the winter thunderstorm season in Japan, a field campaign was conducted to observe radiation bursts associated with lightning discharges with the use of a NaI scintillator and a thin plasticExpand

Energetic Radiation and Lightning
Until very recently, lightning was thought to be an entirely conventional discharge, involving only low-energy (a few eV) electrons. This picture changed with the discovery of intense x-ray emissionExpand
A ground level gamma‐ray burst observed in association with rocket‐triggered lightning
energetic radiation was observed at much earlier times, up to 160 ms before the return strokes. Because for such times, the dart leader tip must have been about 1000 m above the ground, it cannot beExpand
The energy spectrum of X-rays from rocket-triggered lightning
Although the production of X-rays from natural and rocket-triggered lightning leaders have been studied in detail over the last 10 years, the energy spectrum of the X-rays has never been wellExpand
A fundamental limit on electric fields in air
[1] By modifying the avalanche mode of runaway breakdown to include positive feedback from gamma-rays and positrons, it is found that enormous bursts of energetic radiation can be produced in strongExpand
Terrestrial gamma ray flash production by lightning current pulses
[1] Terrestrial gamma ray flashes (TGFs) are brief bursts of gamma rays observed by satellites, typically in coincidence with detectable lightning. We incorporate TGF observations and the key physicsExpand
The initiation of lightning by runaway air breakdown
[1] A mechanism for lightning initiation by the sustained runaway breakdown of air is presented. Unlike earlier models that rely upon large cosmic-ray air showers, this mechanism uses the runawayExpand
Origin of neutron flux increases observed in correlation with lightning
[1] The past decade of research into the phenomenon of lightning has seen an accumulation of evidence for the existence of penetrating radiation (X- and γ-rays) in direct association with many formsExpand
Quenching electron runaway in positive high-voltage-impulse discharges in air by laser filaments.
TLDR
Strong hard x rays being observed from impulse atmospheric discharges with maximal voltages from U=0.5 to 0.9 MV just before the breakdown were completely stopped with the use of femtosecond-laser-filament plasma, suggesting a preheating mechanism for formation of the electron runaway in air.
