内容記述タイプ | Abstract | |||||
内容記述 | The collective Thomson scattering (CTS) technique has been utilized with the backscattering configuration to diagnose the bulk and fast ions in the Large Helical Device (LHD). The spectrogram of the scattered radiation presents the transient phenomena related to fast ion slowing down in auxiliary neutral beam heated plasmas. This is obtained by the broad band receiver resolving with 32 channels, while the probing beam from 77 GHz gyrotron is modulated with 50 Hz and is injected into plasmas. In the same shot, especially in low temperature plasma (Te, Ti < 1 keV), a wave excitation is also observed in a narrow frequency band. The peaks in the CTS spectrum exist between 0.5 and 1.0 GHz and are observed in both frequency sides asymmetry. For the forthcoming experiments, the feasibility of CTS diagnostics at a new port location is assessed to extend the diagnostic capability for measuring the ion velocity components. Expected spectra for scattered radiation are the same signal level as the present location from a numerical calculation. | |||||
