Abstract
Plasma diagnostics play an important role in controlled fusion research. In this study, we developed an automated optical emission spectroscopy (OES) system for assessing plasma composition and density. The OES method for determining the electron density is based on the linear Stark effect [1]. A special feature of the system is its own unique algorithm for recording radiation, mathematical calculations and displaying the final parameters of beam-plasma discharge (BPD) on the screen in real time. Determining impurities on the eroded surface of materials when exposed to plasma was also one of the tasks of this diagnostic system.
