Research Abstract

In this study, the experimental observation of the time evolution of electron density ne, electron temperature T_e, electron velocity distribution function. f_e(υ), and hydrogen Balmer series spectra in hydrogen recombination plasma have been carried out in a liner plasma device. The value of n_e, T_e, f_e(υ), and hydrogen Balmer series spectra is found to depend on gas pressure in the recombination plasma with pulse plasma flow. The high energy electrons in the pulse plasma flow are influenced by the time evolution of the Balmer series spectra. The transient behavior of the recombination plasma with pulse plasma flow has been studied by observing the short double minimum(negative) spike in Hα emission from the plasma. This response in Hα emission is explained by CR model taking into account of the high energy electron associated with pulse plasma flow.
