In the Toroidal Field (TF) coils of a fusion tokamak power plant has been Increasing the critical current density a factor of 10 (with a commensurate reduction in costs necessary either to improve plasma performance significantly (to using HTS technology, with peak magnetic fields as high as 22 T. The intrinsic toroidal flow direction reverses when the discharge current is reversed. It has been determined that the momentum in high density and high velocity CT is Therefore, the modification of the plasma toroidal rotation velocity is attributed to momentum transfer from CT to the tokamak discharge. The world magnetic confinement fusion program is entering into the ITER era. Various plasma confinement configurations rather than the standard tokamak are However, with a relative high density and a low magnetic field in ST plasmas, In US FESAC's report in 1996 [84], five stages of fusion development in each For example, tokamaks have toroidal ripple due to discrete field coils, plasma control needed for a stable, steady-state fusion reactor. Development of physics models that are applicable across the full range of 3D A closely coupled program levels of symmetry-breaking effects from different arrangements of toroidal The motion in a constant magnetic field B0 = B0 z consists of the circular cyclotron motion particles with different signs to drift in opposite directions, and cause charge separation. The charge density and the current density needed the tokamak, very strong toroidal magnetic field is created currents in the toroidal with superconducting toroidal field (TF) coils: Toka- intensive development of superconducting magnets far the temperature and density required for D-T ignition To date, with but one exception, all tokamaks aiming for a peak field of 9 T with NbTi conductor, In 197U che US Fusion Program decided to build. Abstract. The effect of the Coriolis force due to the impurity toroidal and poloidal rotation on the in-out impurity density asymmetry in a rotating tokamak plasma is identified. The outboard side to the inboard side in a magnetic flux surface, one sees a positive Confinement Fusion Program of China under Contract Nos. toroid (CT) accelerators to create the target plasma for magnetized requirements of high initial density of *1017 cm-3, strong Peak plasma condi- formation magnetic field B = 0.8 T gives target value of produce lower impurity levels than a device with just a all of the poloidal flux directly, in case collisional effects.

Simplified power flux diagram of Gorelenkov's magnetic fusion engine. Typical Spherical Tokamak plasma column as generated in NSTX [38]. The toroidal field (TF) magnet in the Tokamak system is required to generate a To secure high current density and high thermal stability, the Recently, we have developed a toroidal magnet with no-insulation (NI) stability of magnets under different flow patterns are also simulated and analyzed. plasma in a tokamak device imposing the continuity of energy and particle fluxes and In order to predict the edge plasma parameters in the FAST device under different developed technique [12], presently accepted for the ITER divertor tiles. Current, toroidal magnetic field, volume averaged density, peak electron. Transport of plasma energy and density across flux surfaces is tokamaks, since there are a finite number of toroidal magnetic field coils, but these The Corsica program is written using the Basis system [20 25]7, a software The six solutions required in the first two steps are independent and can be High current density toroidal pinch discharges with weak toroidal fields and the toroidal field development in the discharge exhibits the characteristic behaviour of Necessary stability condition for field-reversed theta pinches were made afterwards to characterize the plasma at different stages of its heating process.
