Summary

The T6 Stalker Tunnel shock tube was previously used to perform emission spectroscopy in the wavelength regime of 350-850 nm to measure radiation in the shock layer. A VUV emission spectroscopic system is currently under development to use on T6 in its steel shock tube mode, with the goal to perform spectroscopy for shots in the speed range 10-15 km.s−1 and for various gas densities. This system was designed to offer fast turn-around, easy calibration and ensure repeatability between experiments. It comprises a telecentric optical system developed using an optimisation approach, and ray tracing simulations were run to observe, quantify and correct optical aberrations.
