Query: Observation of the ion-ion instability and its suppression mechanism in
  a dusty double plasma device   Ion-ion instability is excited due to the counter streaming of ion beams in
any plasma system. An experiment has been carried out to observe the ion-ion
instability in dusty plasma and in presence of different gas compositions viz.,
H2, Ar, Xe and He. The experiment is performed in a double plasma device
consisting of 90 cm in diameter and 120 cm in length and separated by a mesh
grid of 81% optical transparency. Glass beads of 10 mm average dust
distributions are used as a dust grains for the whole set of experiment and are
allowed to fall within a particular region of plasma column inside the system.
The growing and suppression of ion-ion instability is observed by translating
the probe spatially with respect to different dust density compositions and
compared the same also in presence of other gasses. The suppression mechanism
of this kind of instability in plasmas was explained by RF pumps[1]. However,
in this experimental finding the suppression phenomena are discussed in terms
of dust density inside the system. The instability is found to be suppressed
completely at a critical dust density (Ndcr). The complete set of experimental
results will be tried to explain with the numerical solution of Van der Pol
Equation.
