Barocio Física, Astronomía y Matemáticas Tokamak Canonical mapping Hamiltonian models Poloidal divertors are, more than ever before, a crucial topic for the advancement of magnetic fusion technology.Due to the often non linear and stochastic nature of the plasma edge phenomena, canonical mapping hasprovided a powerful method at modelling their characteristics, albeit many authors rely on heuristically adaptedschemes. Thus, it is reported here a specific and physically consistent map model of the tokamak single nullmagnetic configuration, assuming plasma-field equilibrium, based on the construction of a fundamental Hamiltonianform. Then, the magnetohydrodynamically non ideal perturbations are introduced through the Rayleighfunction of the system. As an illustration, the resulting compact canonical map is applied to the analysis of someof the most relevant features of the edge magnetic topology. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46403614 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2B Vol.36 |
