Abstract:

The temporal and spectral shape and the absolute flux level of particle pulses precipitated by a VLF transmitter are examined from a theoretical point of view. A test-particle model of the gyroresonant wave- particle interaction is applied to the parameters of the observed cases for calculating the precipitation characteristics. The temporal shapes of the precipitation pulses are found to be controlled 1 by the pitch angle dependence of the particle distribution near the edge of the loss cone and 2 by the multiple interaction of the particles with the waves due to significant atmospheric backscatter.
