Abstract
The IGNITOR experiment is designed to produce a significant amount of fusion power. Previous predictions of the machine performance were done in flat-top conditions for plasma current and toroidal magnetic field. This paper presents some results obtained from dynamic simulations of the plasma ramp-up and flat-top phases, with an enhanced version of the JETTO code. The temperature, electron and primary ion density, and current density profile are evolved self-consistently in time, together with the shape and the position of the free-boundary plasma. The equilibrium configurations obtained are consistent with the ones evaluated for the poloidal field coil design. The nominal machine and plasma parameters and the different scenarios planned for the current IGNITOR design were considered, including the most advanced one with I{sub p} = 12MA and B{sub t} = 13T. Different plasma growth scenarios were analyzed to optimize the global plasma performance. In particular, the effect of the rate of rise of the plasma current, toroidal magnetic field and plasma density are discussed. The results confirm that a carefully programmed ramp-up of the plasma current allows tokamak reactors to reach fusion regimes where the q < 1 region represents a small fraction of the plasma cross-section.
