  • Abstract

    Transport barriers of magnetic field lines play an important role in tokamak plasmas. Through devices that cause external perturbations, which may be an ergodic limiter, which disturbs rational surfaces at the edge of the plasma column, it is possible to produce a chaotic layer. Using a Hamiltonian formulation, we investigate the escape of the magnetic field lines towards the walls of t...

  • Abstract

    Transport barriers in magnetic field lines have a significant role in fusion tokamak area. Through devices that cause external perturbations, which may be an ergodic limiter, which cause perturbation in surfaces at the edge of the plasma column, the formation of a stochastic layer is possible. We intend to take a methodology described in previous works to include the effects of the plas...

    Fusion plasma applications and modeling of low temperature plasmas, AP.R

  • Abstract

    Transport barriers of the magnetic field lines have an important role in the controlled fusion in tokamaks. Through the devices that cause external perturbations, which can be an ergodic magnetic limiter, which perturbs rational surfaces at the edge of the plasma column, it is possible to form a layer with chaotic lines in this region. With non-monotonic safety factor profile we have th...

    Transport of magnetic field lines and particles in tokamaks and plasma modeling for deposition and etching, AP.R

  • Abstract

    Magnetic field line transport barriers have an important role in controlled fusion in tokamaks. Through devices that cause external perturbations, which may be an ergodic limiter, rational surfaces can be destroyed at the edge of the plasma column. In this way it is possible to have a stochastic layer. With a non monotonic safety factor profile it is possible to obtain the formation of ...

  • Abstract

    In the Plan of Action 2007 - 2010 MCT is expected to invest in future technologies within the Brazilian Nuclear Program, in particular nuclear fusion. To implement this action, the Ministry created the National Network of Fusion - RNF, with funding initially provided through the project of order of FINEP, which is in final stage of implementation. The agreement Brazil - EURATOM was esta...
