Relativistic electron beam propagation in the Earth's atmosphere: Modeling results

Relativistic electron beam propagation in the earth's atmosphere- modeling results

Linear accelerators (linacs), capable of producing 5 MeV energy electron beams at 80 mA currents, are now down to a size that allow them to be flown on sounding rockets or balloons. This opens up new opportunities for atmospheric/ionospheric modification experiments where the mesosphere and thermosphere regions of the atmosphere can be perturbed down to 40 km altitude. In this paper beam propag...

Chaotic electron dynamics for relativistic-electron-beam propagation through a planar wiggler magnetic field.

It is shown that the motion of an individual test electron in a low-density relativistic electron beam propagating through a realizable planar-wiggler magnetic field is nonintegrable and can become chaotic. The chaoticity, which is induced by the transverse spatial inhomogeneities in the wiggler field, poses limits on the wiggler field amplitude and the beam size for beam propagation and free e...

Analyzing the Propagation Behavior of a Gaussian Laser Beam through Seawater and Comparing with Atmosphere

Study of the beam propagation behavior through oceanic media is a challenging subject. In this paper, based on generalized Collins integral, the mean irradiance profile of Gaussian laser beam propagation through ocean is investigated. Power In Special Bucket (PIB) is calculated. Using analytical expressions and calculating seawater transmission, the effects of absorption and scattering on beam ...

Propagation of a Focused Laser Beam in a Turbulent Atmosphere

Propagation of Partially Coherent Beam in Turbulent Atmosphere: A Review

Partially coherent beam is preferred in many applications, such as free-space optical communications, remote sensing, active laser radar systems, etc., due to its resistance to the deleterious effects of atmospheric turbulence. In this paper, after presenting a historical overview on propagation of optical beams in turbulent atmosphere, we describe the basic theory for treating the propagation ...
