DETERMINATION OF TRANSIENT GAS CONSTITUENT CONCENTRATIONS UTILIZING A HIGH ENERGY ELECTRON BEAM

Abstract

In order to determine the available test time in a helium driven shock tunnel, an interface detection system was developed to indicate the arrival of helium driver gas at the test section. This is done by exciting the gas at the test section with a high energy electron beam and spectroscopically analyzing the resulting fluorescence to determine the helium concentration. Relative values of helium and air emission intensities are calculated and compared with experimental data from both static and transient gas mixtures.
