Abstract

To study the radiation properties of the plasma generated by the explosion of a composite metal bridge foil, the atomic emission spectrometry technique was used to measure continuous plasma emission spectra at different times. The evolution law of the plasma radiation was analyzed, and the plasma composition and ionization were given. The plasma temperatures at different times were calculated using the Boltzmann multispectral slope method, and the maximum temperature was found to be as high as 14 862 K. The evolution law of the plasma temperature versus time was obtained. The plasma electron densities at different times were calculated using the Stark broadening effect. The electron density was found to be in the range of 3.1 × 10¹⁶cm^-3-7.0 × 10¹⁶cm^-3. The plasmas produced by the explosion of the metal bridge foil satisfy local thermodynamic equilibrium conditions.
