A fast camera clearly detected a simple helical structure in the visible-light emission region in the reversed field pinch (RFP) configuration. The observed structure is consistent with magnetic field structures deduced from magnetic measurements with the help of equilibrium reconstruction. The observed simple structure is probably an indication of the internally resonant kink mode structure in a low aspect ratio RFP configuration.
