説明

<p>A new method of vector tomography by laser-induced fluorescence (LIF) spectroscopy is proposed for the evaluation of the velocity field of quasi-coherent structure in linear magnetized plasma. Here, the two-dimensional velocity field was reconstructed with measuring synchronization of azimuthal reference probes and line-integrated LIF. The laser installation condition is designed to move in a radial direction perpendicular to the laser path. We applied the proposed method to a quasi-coherent flow obtained from a direct numerical turbulence simulation and demonstrated that the Reynolds stress and its force can be evaluated if its flow structure is maintained.</p>
