Non-Twist Field Line Mappings for Tokamaks with Reversed Magnetic Shear
The structure of magnetic field lines in a tokamak with reversed magnetic shear is investigated by means of analytically derived area-preserving non-twist Poincaré maps. The basic configuration is the magnetic field produced by an ergodic limiter, superimposed to the tokamak equilibrium field in suitable coordinates. We consider the cases of one and two resonant modes, focusing on magnetic isla...
متن کاملMagnetic Turbulence in Tokamaks
-From a discussion of the disruption process, it is concluded that this process plausibly consists of the onset of a fine grain turbulence. This turbulence must be able to produce the large 1 aly values of the inductive electric field which are associated with the reorganization of the c at poloidal flux Y(r) and the current density Z(r) on the magnetic surfaces of radius r. It is then plausibl...
متن کاملControl of Chaotic Magnetic Fields in Tokamaks
Chaotic magnetic eld lines play an important role in plasma con nement by tokamaks. They can either be generated in the plasma as a result of natural instabilities or arti cially produced by external conductors, like resonant helical windings and ergodic magnetic limiters. This is a review of works carried out at the Universidade de S~ao Paulo and Universidade Federal do Paran a on theoretical ...
متن کاملDesignated magnetic field design for magnetic drug guidance in BNCT
In this paper, a local magnetic field was designed and simulated using a Helmholtz coil along with a ferromagnetic core with an appropriate geometric Structure to concentrate a magnetic flux. This field can be used for magnetic guiding of Boron-borne drugs in BNCT.
متن کاملStructural Design of High Field Tokamaks
Interest in high field non-superconducting tokamaks was strong after the US left the ITER project at the end of 1999. This class of tokamaks, including Alcator C-Mod, IGNITOR, and FIRE, has many challenging and interesting structural characteristics. Structural behavior of these tokamaks is discussed along with the special structural features employed to sustain the huge loads resulting from th...
