Calculation of the energy deposition of electron cyclotron waves in a stellarator plasma

Based on a three-dimensional ray-tracing code, the energy deposition profiles of the electron cyclotron O-mode and X-mode at the first harmonic are calculated. The finite antenna aperture is taken into account. The energy deposition profiles are given in one dimensional form, which is related to the magnetic surfaces and can be used in transport code. The effects of the antenna aperture, the oblique angle of the axis of the antenna to the meridian plane or to the equatorial plane and the plasma parameters to the energy deposition are studied.
