Radial Profile Measurements of Plasma Parameters in the Central Cell of the Hanbit Mirror Device

Radial profiles of plasma parameters (such as electron temperature, plasma density and floating potential) are measured in the central cell of the Hanbit mirror device. The different shaped profiles are obtained by varying the applied magnetic field in the experiment. Thus, the relation between values of plasma beta and the slope of the profile is qualitatively investigated by using measured data obtained at different magnetic fields. In addition, the characteristics of the magnetic fluctuations (less than few ten kHz) in the experiment are investigated. The experimental investigations from the measurements at different applied magnetic fields are presented.
