On the Validity of Two-Chamber Configuration for the Generation of Electromotive Force in Photoplasma

This study investigates different geometry configurations for obtaining photoplasma in a gas cell of Na-Ar mixture. For this purpose, 2-D simulations with the fluid model of plasma have been conducted for single-chamber and two-chamber cells. For the studied range of pressure, the drift-diffusion approximation has been used. The simulation model is based on solving the continuity, momentum balance for charged particles, coupled with electron energy balance equation and the Poisson equation. Detailed plasma chemistry has been considered, and plasma parameters have been obtained, such as electron density and temperature, and the electric potential of the plasma. The obtained results show the effectiveness of the two-chamber cell configuration over the single-chamber one in generating a notable electromotive force (EMF).
