Simulation of Cyclic Operation of a Gas Panel Device

This paper presents a numerical simulation model for the operation of a gas panel discharge cell with a neon-argon mixture. The model is based on a Townsend avalanche or direct ionization mechanism and secondary emission, as well as Penning collisions or indirect ionization. Charges on the dielectric walls are included, but space-charge field distortion is neglected. Cyclic operation of the cell is studied in detail and the effects of geometric and electrical parameters (e.g., gap and pulse widths) on the operating characteristics of the cell (e.g., write, sustain and erase voltages) have been obtained. The results are in good agreement with experimental data where available.
