The paper presents the results of spectroscopic studies of the initial segment of a supersonic plasma jet formed by a pulsed discharge in a capillary made of carbon-containing polymer. Detection of the emission properties of the high-temperature core of the jet (the intensities and contours of the Hα and Hβ Balmer lines and the relative intensities of C II ion lines) with high temporal (1–50 μs) and spatial (30–50 μm) resolutions allowed the authors to reveal specific features of the longitudinal distributions of the electron density and temperature caused by the flow nonisobaricity along the initial segment of the supersonic jet.
