Parametric investigation of nonlinear fluctuations in a dc glow discharge plasma
Glow discharge plasmas exhibit various types of self excited oscillations for
different initial conditions like discharge voltages and filling pressures. The
behavior of such oscillations associated with the anode glow have been
investigated using nonlinear techniques like correlation dimension, largest
Lyapunov exponent etc. It is seen that these oscillations go to an ordered
state from a chaotic state with increase in input energy i.e. with discharge
voltages implying occurrence of inverse bifurcations. These results are
different from the other observations wherein the fluctuations have been
observed to go from ordered to chaotic state.Comment: Submitted to Chao
