Abstract
The electron beam fluorescence technique used exclusively up to now in low density wind tunnels and shock tubes to measure gas density and temperature has been applied to local mass density measurements in the wake of hypersonic models launched in free flight hyperballistic ranges. The advantages and limitations of the technique in this application are discussed. The experimental apparatus is described and the signal analysis scheme is presented. Typical measurements of the mass density obtained in laminar as well as in turbulent wakes show the capabilities of the technique.
