• This project, we have optimized the plasma production experimental technique and
• have obtained some of the plasma fluctuations. We have also performed the experiment for the
• Paschen’s curve which is in accordance with the Paschen’s Law.
• Also, employed some non-linear analysis tools to investigate the underlying dynamics of
• such fluctuations, such as FFT and Phase Space reconstruction of the time series data from
• the plasma system along with the Recurrence Plots and determination of the Embedding
• Dimension. We also saw the application of Singular Value Decomposition as a tool to filter the noise from the data.
