Measurements of Parallel and Poloidal Velocity by Using Visco-Mach Probe in Hanbit Mirror Device

초록

To understand the edge plasma parameters in the central cell region of Hanbit mirror device, a modified Mach probe is used to measure the parallel along the field and poloidal velocity by rotating the probe. The Mach probe was attached on the fast injection system, which can scan the central cell region of Hanbit device in the radial direction. The experimental data from the modified Mach and will be presented and driving force of the plasma flow will be discussed along with the Mach probe theory
