Design and Development of Plasma Window Using Microhollow Cathode Discharge

Search this article

Description

<p>A plasma window is an atmosphere-vacuum interface, formed by the interaction of the ideal gas pressure effect and dynamic viscosity effect of plasma. The application of a plasma window is the generation of a pressure difference between 1 and 7 × 103 Pa without a large exhaust system. In this study, we designed an apparatus with a microhollow cathode discharge for plasma window generation. A resulting pressure difference between 0.889 and 8 × 103 Pa and a pressure ratio of approximately 104 were obtained.</p>
