Owing to its electrostatic properties, the rate of the parametric growth of the kinetic Alfven wave (Alfven wave with lambda identical with k/sup 2//sub perpendicular/ c/sup 2//sub s/..omega../sup 2//sub ci/ approximately 0 (1)) is shown to be larger than that of the classic result by a factor of lambda..omega../sub ci//..omega../sub A/ where ..omega../sub ci/, ..omega../sub A/ are the ion cyclotron and the Alfven frequencies, k/sub perpendicular/ is the perpendicular wave number and c/sub s/ is the ion sound speed. This fact can be utilized to heat a plasma with a tokamak-type parameter.
