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...

متن کاملSpace Experiments with Particle Accelerators: Sepac
The Space Experiments with Particle Accelerators (SEPAC), which flew on the ATLAS 1 mission, used new techniques to study natural phenomena in the Earth's upper atmosphere, ionosphere and magnetosphere by introducing energetic perturbations into the system from a high power electron beam with known characteristics. Properties of auroras were studied by directing the electron beam into the upper...
متن کاملAtomic and Molecular Properties of Metals from Artificial Cloud Experiments in the Upper Atmosphere
Time and frequency resolved observations of metal vapor clouds in the upper atmosphere can be used to obtain information on atomic and molecular properties of the metals involved, e. g. atomic transition probabilities, photoionization cross sections, chemical reactivity of atoms in the ground state and in excited states. Experimental techniques of evaporation, the methods of obser vation and s...
متن کاملWaves in Pluto’s Upper Atmosphere
Observations of the 2007 March 18 occultation of the star P445.3 (2UCAC 25823784; R = 15.3) by Pluto were obtained at high time resolution at five sites across the western United States and reduced to produce light curves for each station using standard aperture photometry. Global models of Pluto’s upper atmosphere are fitted simultaneously to all resulting light curves. The results of these mo...
