We present an ionic kinetics study by time resolved Laser Induced Fluorescence of radial transport in a linear magnetized plasma device. A spiral arm, extending outside the ionization region, is in constant rotation, with a rotating frequency lower than ion cyclotronic frequency, but ion kinetics exhibits a complex behavior: azimuthal ion velocity is constant and radial velocity.growths linearly with respect to the radius. Electric field is also computed and the mean ion velocity does not.show a simple êxB structure. Flux exhibits a radial transport to conserve the ionizing electron current injected in the bulk plasma.
