Abstract

A large diameter plasma window was developed for accelerator applications. In this study, a pressure separation using the plasma window was demonstrated, and the maximum diameter of the plasma window reached up to 20 mm. The prediction formula based on the viscous flow for confinement pressure cannot be applied in the case of large diameters due to low input power density to the plasma.
