title = "Coherent Anti-Stokes Raman Scattering Thermometry and CO Concentration Measurements in Plasmatron X",
abstract = "We present coherent anti-Stokes Raman scattering thermometry and relative carbon monoxide concentration measurements acquired under low-pressure conditions in the Plasamtron X plasma wind-tunnel facility. Free-stream nitrogen CARS thermometry indicates a consistent mean free-stream temperature of T = 4973 ± 133 K, for pressures of 100-200 mbar at 55 kW plasma power. Wall-normal profiles of temperature and CO concentration are demonstrated within the boundary layer of an ablating graphite sample at the same 55 kW power at 200 mbar pressure and near-wall CARS spectra are successfully recorded at pressure as low as 100 mbar. The CARS instrument enables spatially precise measurements of mean temperature and CO to within ~50-100 m of the graphite surface.",
