Abstract :
In a krypton plasma, the growth of dust particles can strongly affect the plasma characteristics by inducing many types of instabilities. These unstable phenomena are studied by analyzing their frequency evolution as a function of time and by emphasizing the appearance of plasma spheroids. Different phases are evidenced due to a detailed analysis of the form and the frequency of the discharge current. Concerning the plasma spheroids, interesting motions in the plasma bulk are evidenced.
