Abstract
The ALTAIR experiment on TORE SUPRA for the analysis of plasma turbulence by CO{sub 2} laser scattering includes some original features: 2{pi} rotation of analysed k wave vectors, heterodyne detection, and accessibility of 2 simultaneous and independent wave numbers. Because of the very small scattering angle, such scattering experiments are usually considered as having no resolution along the beam. If we take into account the pitch angle of the magnetic field lines together with the fact that the fluctuation wave vectors are mainly perpendicular to these field lines, one can improve the spatial resolution along the chord of measurement. Results, for measurements with k ranging from 3 to 15 cm{sup -1}, showing this resolution are presented. Using a suitable deconvolution method, density fluctuation profiles have been determined.
