- Abstract
- Ion saturation currents of a Hanbit mirror plasma measured by Langmuir probes, which are located at the edge of the plasma, have been analyzed by using the wavelet bispectral method. The bispectral analysis of low-frequency electrostatic turbulence shows a strong bicoherence at very low frequency, which indicates resonant three-wave coupling between the low-frequency modes in the phase space.
