[en] The transport of a tokamak plasma which has been freed from contact with a material limiter is studied. A small compression in major radius of the plasma in the ATC tokamak produced a free-standing discharge, similar except for scale to a possible configuration of the Tokamak Fusion Test Reactor. Diffusion speeds in the range 10 ms^-1 were measured, and the evolution is readily modeled by a numerical transport model calculation. The experiment provides a successful preliminary test of the feasibility of this technique
