Two-dimensional kinetic full wave analysis of ICRF waves using integral form of dielectric tensor

POSTER

Abstract

In order to describe the two-dimensional wave structure and power deposition profile of ion cyclotron waves in magnetized plasmas, full wave analysis using the integral form of dielectric tensor has been extended to two dimensional configurations. The integral form of the dielectric tensor includes three types of kernel function, such as Plasma Dispersion Kernel Function (PDKF), Plasma Gyro Kinetic Function (PGKF), and Parabolic Plasma Dispersion Kernel Function (PPDKF). Inhomogeneity of magnetic field strength along the field line as well as the finite gyro radius effect are consistently take into account. Finite element method taking account of the coupling of elements along particle orbits is utilized. In a tokamak configuration, cases of minority-ion heating and second-order harmonic heating comparison are compared with those of conventional differential operator approaches. Coupling with the short-wave-length ion Bernstein waves and the interaction with energetic ions are discussed. Application to axisymmetric mirror configurations will be also presented.
