Le résumé fourni par la source

This article investigates the influence of toroidal characteristics on vertical charge separation in electron cyclotron resonance (ECR)-produced plasma within a toroidal plasma device featuring a tight aspect ratio and higher toroidicity. Conducting experiments in the simple tight aspect ratio machine assembly (STARMA), the study measures the vertical electric field induced by curvature and gradient drift to comprehend the effect and characteristics of vertical charge separation. Preliminary results from STARMA, distinguished by a high toroidicity and a curvature ($\kappa $) of 9.6 m−1, reveal a significant impact of toroidal field (TF) characteristics on charge separation in the vertical direction. The article presents initial experimental findings, emphasizing the temperature and density profiles of ECR-produced plasma within the device, possible O-X mode conversion, and charge separation due to gradient and curvature of magnetic field. The distinctive design and features of device provide a unique platform for in-depth investigations into plasma behavior, contributing to advancements in controlled plasma systems, with potential applications in fusion research and material processing.
