Abstract
Two different methods for the creation of low-frequency waves in the d rift plasma frequency range (f(d) approximate to 20-50 kHz) have been investigated in the TAU-1 device. The first method is based on the bea t process between two initially excited oblique Langmuir waves, when t he frequency of the beat wave is near the draft plasma frequency. The second method is based on the modulation of the initial excited obliqu e Langmuir wave by a low-frequency signal (f approximate to f(d)). The shape of the frequency spectra is significantly modified by the prese nce of the externally excited waves.
