The plasma fluctuation in an MHD channel affects the durability of the channel and is also important for the stable extraction of electric power from the generator. To clarify the characteristics of fluctuation. Plasma parameters should be measured accurately, and the diagnostic methods for measuring the seed atom density are needed. The purpose of the present research is to develop the laser-aided diagnostic method which is nonintrusive and has high apatial and temporal resolution. The laser-induced fluorescence (LIF) method is developed to measure the plasma fluctuation in an MHD channel. In this method, sodium contained as impurity in the potassium seed is used as a seed tracer, and sodium atoms are excited with the dye laser. The LIF from the MHD plasma is detected successfully with very high S/N ratio. The detected LIF signal is transmitted to the data acquisition system, and the power spectrum is calculated with the fast Fourier transformation program. With this system, the Characteristics of the MHD plasma fluctuation are clarified.
