摘要：
The article presents the results of high-speed spectral measurements of the emission spectrum of plasma-vortex formations formed by an atmospheric pulsed plasma torch based on an electrical explosion of a conductor. Spectrum registration is carried out in the stage of autonomous existence of vortex formations. It is shown that the emission spectrum contains the Planck continuum, due to the presence of condensed oxides, and the molecular bands of AlO. Based on the obtained data, the dependence of the temperature dynamics over time was obtainedby the method of spectral pyrometry.
