| 内容記述 | The structure of the continuous spectra of shear Alfven and ion sound waves in a beam-driven high-beta JT-60U plasma are analyzed using the linear gyrokinetic code LIGKA. In the presence of fast ions, new continuous spectra are found, which seem to arise from the modification of shear Alfven branches by the fast ion sound speed. Evidence for Alfven-acoustic couplings in the Alfven continuum band (w_BAE <~ w <~ w_TAE) is reported and implications for anomalous bulk ion heating are discussed. | |||||
