N2 - Results are presented for a Krypton Tagging Velocimetry (KTV) investigation of the freestream flow of the T5 reflected shock tunnel at Caltech. This KTV scheme utilizes two-photon excitation at 216.67 nm with a pulsed dye laser, followed by re-excitation at 769.4547 nm with a continuous laser diode. Results are presented for experiments performed in 97% N2/3% Kr and 99% N2/1% Kr gas mixtures at a unit Reynolds number of approximately 4×106 m−1 and a reservoir mass-specific enthalpy of approximately 5 MJ/kg. Agreement between the KTV derived velocity measurement and the computational results is excellent, within the uncertainty of the experiment.
