Bohm like transport in a toroidal magnetoplasma in the absence of longitudinal current

Measurements of turbulent transport produced by electrostatic (e.s.) fluctu ations and of the global particle transport have been carried out in the Si mple Magnetized Torus Thorello. The turbulent particle transport comes out to be of the same order as that calculated from a Bohm diffusion coefficien t. The experiments suggest that spontaneously generated turbulence plays an important role in the steady state plasma confinement.
