Abstract

We have observed self-generated chaotic current oscillations in the plasma of a helium glow discharge. The S(f) power density spectrum of the current signal exhibited characteristic S(f) ∝ 1/fα dependence over a wide range of frequencies with an exponent of α = 4.3. The correlation dimension of the system determined from the correlation sums of the current signal was found to be D2 ≅ 6.3. This value of D2 is in good agreement with the theoretically predicted dimension, corresponding to fully developed turbulence.
