Energy confinement in FTU ohmic plasma
This paper presents energy confinement data for FTU deuterium plasma in ohmic regime, discussing in detail the role of the ion transport and the scaling of confinement with the toroidal magnetic field. New experimental data on ion temperature are presented and their analysis shows that, taking into account the experimental error bars, a role of the ion transport in the saturated energy confinement cannot be excluded, even with an ion thermal diffusivity less than or equal to 3 times the neoclassical value. The magnetic field dependence of the energy confinement is shown to be weak, from the analysis of experimental results at 2.5, 4, 6 and 7 T. The scalings of the relevant plasma quantities with the magnetic field are also presented.
