Time-dependent of recombining Plasma with Pulse Plasma flow

The time evolution of electron density n$_{e}$, electron temperature T$_{e}$, electron velocity distribution function \textbf{\textit{?}}$_{e}(\upsilon)$, and hydrogen Balmer series spectra is found to depend on gas pressure in the recombination plasma with pulse plasma flow. The pulse plasma flux is generated by controlling the electric circuits of electrodes of plasma source. The negative spikes were appeared in the time evolution of the Balmer series spectra, which indicate on the transition from ionizing to recombining plasma.
