摘要
Heating finite betas(relative to low beta)tokamak plasmas by Alfven waves is studied by means of a linearized kinetic model which takes into account ion sound and transit time magnetic pumping as well as the effect considered by preceding authors.In cylindrical geometry,a set of three second-order differential equations in r for the perturbed fields Er,E_(⊥),and E_(||) is solved numerically.The results lead to a significant conclusion that Alfven wave heating may be an advanced way of heating plasmas in future tokamaks.
