Particle-in-cell plasma simulations of the modified two-stream instability

| description | We model the modified two-stream plasma
instability occurring in the ionospheric E-region using a 2.5-dimensional
particle-in-cell code. Compared to previous similar work we concentrate on
simulated quantities that can easily be measured in the real ionosphere by
coherent radars or rockets, such as the Doppler velocity, the backscattered
power, backscattered spectra, aspect angle behaviour and electron temperature
enhancement. Despite using a relatively small simulation model, we obtain
remarkably good agreement between actual observed and simulated plasma
parameters. The advantage of such a small system is that we were able to perform
(other than in previous related work) many simulation runs with different sets
of input parameters, thus studying the unstable plasma under various conditions. |
