Streamer Propagation

Glow discharges are being used in many fields of application. For the improvement of performance in these applications, it is necessary to understand discharge dynamics experimentally and numerically. In this paper, a Monte Carlo simulation is carried out in oxygen ( O 2) in uniform electric fields. The electron motion and avalanche growth are simulated by tracing individual paths, and the technique also accounts for the effect of the rapid spatial and temporal space charge variations by solving the Poisson equation. The streamer propagation, electron, positive and negative-ion distribution, and space charge fields are studied in detail as time increases.

This work is devoted to the modeling of space charge dominated particle beams in the paraxial approximation with several types of external focusing fields (uniform, periodic and alternating gradient). A solid mathematical background for numerical beam simulation is established. The Kapchinsky–Vladimirsky (KV) distribution which can be matched exactly or numerically to the focusing channel is first studied. Then the matched KV beam is used to approximately match arbitrary beams. Moreover, Waterbag and Maxwell–Boltzmann beams are studied to give analytical solution for code validation. Finally, numerical simulations are presented in different configurations.
