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… 

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 plastic

High energy photon and electron bursts associated with upward lightning strokes

We conducted a field campaign during the Japanese winter thunderstorm season to observe radiation bursts associated with lightning discharges using a NaI scintillator and a thin plastic scintillator

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 emission

A fundamental limit on electric fields in air

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 strong

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 physics

The initiation of lightning by runaway air breakdown

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 runaway

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 forms

A ground level gamma‐ray burst observed in association with rocket‐triggered lightning

We report the observation of an intense gamma‐ray burst observed on the ground at sea level, produced in association with the initial‐stage of rocket‐triggered lightning at the International Center

Quenching electron runaway in positive high-voltage-impulse discharges in air by laser filaments.

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.

Terrestrial gamma ray flashes with energies up to 100 MeV produced by nonequilibrium acceleration of electrons in lightning

[1] Using Monte Carlo models simulating energetic electrons in inhomogeneous electric field and the transport of energetic photons in the Earth's atmosphere, we show that the spectrum of



Energetic radiation associated with lightning stepped‐leaders

With the use of a NaI scintillation detector, bursts of radiation with energies in excess of 1 MeV were recorded at a mountain‐top observatory immediately before three, nearby cloud‐to‐ground,

X-ray enhancements detected during thunderstorm and lightning activities

An X-ray detector has been flown on-board a NASA F-106 jet into thunderstorms. We have concluded that significant quantities of 3 to >12 keV X-rays are produced within thunderstorm clouds which

Discovery of Intense Gamma-Ray Flashes of Atmospheric Origin

Detectors aboard the Compton Gamma Ray Observatory have observed an unexplained terrestrial phenomenon: brief, intense flashes of gamma rays. These flashes must originate in the atmosphere at

Ground‐based search for X rays generated by thunderstorms and lightning

A series of ground-based experiments have been performed to investigate gamma ray/X ray count rate increases that are associated with thunderstorm and lightning activity. NaI scintillation detectors

Further observations of X-rays inside thunderstorms

A control and an x-ray detector were flown into thunderstorms in 1984. The x-ray detector found statistically significant radiation flux increases in the energy range 5 to > 110 keV for time

Initial results from simultaneous observation of X‐rays and electric fields in a thunderstorm

With an X ray detector designed for flight on a free balloon, we obtained a sounding of X ray intensity and electric-field strength in a mesoscale convective system (MCS) near Norman, Oklahoma, in

As is well illustrated by photographs of their tracks, the majority of β-particles of given initial velocity bave approximately the same range, measured along the path. When the track shows a visible

Temporal and spectral characteristics of terrestrial gamma flashes

We have analyzed the Burst and Transient Source Experiment (BATSE) high-resolution timing data for 13 terrestrial gamma flashes (TGFs) to better characterize this newly identified phenomenon, which

Gamma‐ray emissions observed in a thunderstorm anvil

Balloon‐borne gamma‐ray and electric‐field‐change instruments were launched into a daytime summer thunderstorm to evaluate a new experimental design to test hypotheses for the production of transient
