Abstract:

Measurements of the absolute intensity of radiation are performed on the continuum and line emission from shock-heated xenon gas. The line radiation measurements are used to determine the maximum gas temperature behind the shock wave. The continuum emission measurements are used to determine the correction factor for the absorption coefficient of xenon and the radiative cooling rates after the maximum temperature is reached. Values of temperature and electron concentration, calculated from measured shock wave velocities and the Rankine-Hugoniot conditions, are used to determine the values of the absorption coefficient. Results are compared with the theoretical calculations of Schluter and of Biberman and Norman, and good agreement is observed. Boundary layer effects behind the shock wave are also considered.
