Abstract:
Plasma is a quasi-neutral gas consist of charged and neutral particles that manifest collective behavior. Plasma is an ionized gas in which all or a significant portion of its atoms have lost one or more electrons and become a set of positive ions and electrons. Plasma is one of the four primary states of matter. This project intends to generate plasma by a pulsed electric discharge in a gaseous environment. At first, in this project, the proper excitation circuits are collected and compared, then based on the feasibility of production, applicable methods are selected and constructed. The construction steps were such that the selected circuits were first simulated with the appropriate software and then constructed. These circuits' operations are tested by external loads, and the results are analyzed, so in the final step, the necessary improvements are made. In this project, we achieved a pulse voltage higher than 1 MV using a series of pulse transformers
