Abstract :
In a DC discharge plasma system, in which two meshes are installed, the current-driven ion acoustic instability is excited when a de potential Vm is applied to one of them. When the instability fully grows, the system reaches a very turbulence state, the so-called ion acoustic turbulence. The experimental measurement of energy distribution function of electrons in ion acoustic turbulence measured by the Langmuir probe shows a non-Maxwellian nature along with electron heating
