Angular distribution of Bremsstrahlung photons and of positrons for calculations of terrestrial gamma-ray flashes and positron beams
Abstract Within thunderstorms electrons can gain energies of up to hundred(s) of MeV. These electrons can create X-rays and gamma-rays as Bremsstrahlung when they collide with air molecules. Here weExpand

Streamer propagation in the atmosphere of Titan and other N2:CH4 mixtures compared to N2:O2 mixtures.
Streamers, thin, ionized plasma channels, form the early stages of lightning discharges. Here we approach the study of extraterrestrial lightning by studying the formation and propagation of streamerExpand

The design of a radio-frequency coaxial resistor
Coaxial resistors used as reflection-free terminations of concentric transmission lines are usually enclosed in a jacket, the characteristic impedance of which is ?3 times lower than the resistance.Expand

Influence of Atmospheric Electric Fields on the Radio Emission from Extensive Air Showers
The atmospheric electric fields in thunderclouds have been shown to significantly modify the intensity and polarization patterns of the radio footprint of cosmic-ray-induced extensive air showers. ...

Radio frequency coaxial resistors are usually fitted with an exponential jacket, whose design is based on an approximation by a cylindrical transmission line. This approach is not consistent with theExpand

The emission of energetic electrons from the complex streamer corona adjacent to leader stepping
We here propose a model to capture the complexity of the streamer corona adjacent to leader stepping and relate it to the production of energetic electrons serving as a source of X-rays andExpand

PPPS-2013: Particle and hybrid modeling of NS pulsed discharges: Discharge structures and electron energies
Summary form only given. ICCD photographs with nanosecond resolution of nanosecond pulsed discharges from a pointed electrode show a characteristic sequence of evolution: first the formation of anExpand
The Effect of a Cathode Impedance on the Frequency Stability of Linear Oscillators

  • Proceedings of the IRE
  • 1960
High stability oscillators usually employ tubes having rather high values of transconductance. Excellent frequency stability as to valve capacitance and supply voltage changes results, but a changeExpand

The Planck length and the constancy of the speed of light in five dimensional space parametrized with two time coordinates
In relativity and quantum field theory, the vacuum speed of light is assumed to be constant; the range of validity of general relativity is determined by the Planck length. However, there has been noExpand
