| Abstract: | In this paper, we present the results of the study of the spectral composition and temporal dynamics of optical emission during electrical explosion of a tungsten wire. It is found that the second emission peak ??1ms long appears at wire diameters exceeding 100 ??m. At the same wire diameters, an intense continuous Plank spectrum is observed in the red region of the optical spectrum. During electrical explosion of wires less than 100 ??m in diameter, the second intensity peak is absent, and the survey spectrum contains only atomic spectral lines. The assumption about the correlation of these two effects is made. |
