N2 - This paper reports the new phenomenon – the presence of electron vortexes in steadily generated two-dimensionalphotoplasma. A fluid model of a two-chamber photoplasma cell with sodium vapor and Argon as a buffer gas has beenconducted in this study. The excitation source is in the first (driver) chamber. The transport processes of the generatedplasma from the first into the second (diffusion) chamber create an electromotive force (EMF), which is the potentialdifference between them. It is shown that, in the two-chamber photoplasma, along with the flows of classical ambipolardiffusion, vortex currents of electrons are also formed. The change in temperature and electron density caused by them couldaffect the potential difference between the two chambers. The dependence of the current vortices and, consequently, thegenerated EMF on the buffer gas pressure is shown.
