Formation Mechanism of Dense High-Speed Plasma Flow in Tapered Capillary Discharge

Abstract: We propose a new type of plasma source using a pinch discharge in a tapered capillary, which generates a dense moving plasma by electromagnetic compression and acceleration. The axial velocity and flux of the moving plasma are controllable and can be maximized by adjusting the taper angle. The behavior can be illustrated with a simple model considering the pinching dynamics of the current sheet. [4] are conventionally used to drive the highspeed flow. However, dense, high-speed flow is difficult to form by hy… Show more

We proposed a new type of plasma source using a z-pinch discharge with a tapered capillary [5]. In this scheme, the current sheet in the tapered capillary not only radially compresses but also axially accelerates the plasma.…”
