The dynamics of dc neon glow discharge is examined by calculating a Lyapunov exponent spectrum

LES and correlation dimension
Dcorr from experimental time series. The embedding theory is
used to reconstruct an attractor with the delay coordinate method. The analysis refers to periodic,
chaotic, and quasi-periodic attractors. The results obtained are confirmed by a comparison with
other methods of time series analysis such as the Fourier power spectrum and autocorrelation
function. The main object of the present work is the positive column of a dc neon glow discharge.
The positive column is an excellent model for the study of a non-linearity plasma system because
it is nonisothermal plasma far from equilibrium.
