Abstract

An overview of the development and implementation of spectroscopic diagnostic techniques for high enthaly facilities (with examples from HEG) is given. Spectrally and spatially resolved results with NO LIF at 193 nm on HEG are given for the free stream and for various models (European HERMES, Japanese HOPE, aerobraking configuration, cylinder, sphere). The problems of luminosity, fluorescence quenching, non-linear effects and corrections needed for aingle shot measurements are discussed with reference to the HEG results and to extensive tests carried out on a sspecially designed heated cell capable of providing controlled NO conditions in a flow system. Other spectroscopic techniques such as emission spectroscopy, tunable diode laser absorption and flash lamp absorption are referred to briefly.
