HANBIT is a magnetic mirror confinement device. Recent physics experimentshave been mainly focused on identifying discharge characteristics and on getting stable plasmaproduction and operation modes, by using a 500 kW slot antenna system at a fixed RF frequency of 3.5MHz and varying discharge conditions such as fueling rate, RF power, and B-field intensity incentral cell. Two distinct operation modes are found to be very sensitive to the RF power as well asthe ratio of the RF frequency to the ion cyclotron frequency. A MHD interchange mode of m = - 1 isclearly observed and the stabilizing mechanism can be explained by the sideband coupling theory.
