  1. 69. A compact FMCW reflectometer/interferometer design for the monitoring of atmosperic entry flows

    Measurement Techniques

    A compact reflectometer has been developed at Instituto de Plasmas e Fus\~{a}o Nuclear for Fusion plasma monitoring applications. This work describes the application of this diagnostic to the conditions and requirements of atmosperic entry flows, where the knowledge of the properties for the plasma surrounding the vehicle is key.

    Indeed, on the next experimental fusion reactors, the number...

  2. 57. How atomic nitrogen overpopulation enhances molecular radiation in a recombining nitrogen flow?

    Workshop Test Cases

    We use optical emission spectroscopy to measure spectrally resolved radiation from a recombining nitrogen plasma for temperatures ranging from 3200 to 7000 K. An inductively coupled plasma torch is used to create an equilibrium plasma, which is then forced to rapidly recombine by flowing through a water-cooled tube. The density of atomic nitrogen is measured and found to be overpopulated. This...

    Measurement Techniques

    A test campaign was performed in the GHIBLI arc jet facility in the framework of the European funded LIGHT-TPS project, devoted to research and development of Ultra-High Temperature Ceramics (UHTC) coatings on Ceramic Matrix Composites (CMC) for super light-weight Thermal Protection Systems (TPS) of space re-entry vehicles.

    Two UHTC coatings made of different zirconium diboride (ZrB2)...

  4. 52. Absolute number density calibration of two-photon induced polarization spectroscopy with atomic oxygen

    Measurement Techniques

    Two-photon induced polarization spectroscopy (TIPS) is a laser diagnostic technique that relies on the simultaneous absorption of two photons, one being contributed by a strong, circularly polarized pump beam and the other by a weaker, linearly polarized probe beam. The two beams are crossed at a slight angle thus defining the measurement volume. Through consideration of the two-photon...
