[en] Measurements have been made of the infra-red emission from 0.6 to 30 μm of exploding wire (CH₂, Cu, W) plasmas produced by the Gamble II generator. These measurements show that most of the plasma radiates as a blackbody in the infra-red region of the spectrum with the addition of intense narrow band radiation near ωsub(pe) (lambda = 10 μm). Particularly, intense nonthermal emission correlates with intense pinch formation, while less intense nonthermal emission correlates with the presence of electron beam-target X-radiation from the wire plasmas. As the initial wire size or atomic number of the wire is reduced, the intensity of the nonthermal emission increases. (author)
