Magnetospheric Chorus Emissions : a Review
A review of chorus emissions observed on ground-based stations and in the Earth’s magnetosphere is presented. Different approaches to modelling these emissions are discussed. It is pointed out that the most likely energy source of chorus emissions lies in the anisotropic hot electrons in the equatorial magnetosphere. The energy of these electrons is transferred to waves via the electron cyclotr...
متن کاملUnique concurrent observations of whistler mode hiss, chorus, and triggered emissions
We present a unique 2 h ground-based observation of concurrent magnetospheric hiss, chorus, VLF triggered emissions as well as ELF/VLF signals generated locally by the High Frequency Active Auroral Research Program (HAARP) facility. Eccentricity of observed wave polarization is used as a criteria to identify magnetospheric emissions and estimate their ionospheric exit points. The observations o...
متن کاملDucted propagation of chorus waves: Cluster observations
Ducted propagation of whistler waves in the terrestrial magnetosphere-ionosphere system was discussed and studied long before the first in-situ spacecraft measurements. While a number of implicit examples of the existence of ducted propagation have been found, direct observation of ducts has been hampered by the low sampling rates of measurements of the plasma density. The present paper is base...
متن کاملMC generators in CHORUS
CHORUS is an experiment primarily designed to search for νμ → ντ oscillations in the CERN wide-band neutrino beam. It also aims to investigate a wide range of charm physics. In four years of exposure, more than 10 neutrino interactions have been accumulated in the emulsion target, out of which several thousands lead to the production of a charmed particle. Using its massive calorimeter as a tar...
متن کاملDependence of the Sweep Rate of Whistler-mode Chorus Emissions on the Plasma Density
Whistler-mode chorus consists of intense electromagnetic wave packets generated by a nonlinear mechanism involving wave-particle interactions. Chorus wave packets are discrete frequency-time structures in a frequency range from a few hundreds of Hz to several kHz changing their frequency on a time scale from a few tenths of seconds to a few seconds. The source region of chorus emissions is loca...
