| 抄録 | Two-dimensional distribution of impurity lines emitted from ergodic layer with stochastic magnetic field lines in Large Helical Device (LHD) has been observed using a space-resolved extreme ultraviolet (EUV) spectrometer. The two-dimensional electron temperature distribution in the ergodic layer is successfully measured from a line intensity ratio of Li-like NeVIII 2s-3p (2S1/2-2P3/2: 88.09 A, 2S1/2-2P1/2: 88.13 A) to 2p-3s (2P1/2-2S1/2: 102.91 A, 2P3/2-2S1/2: 103.09 A) transitions. The intensity ratio analyzed with ADAS code shows no dependence on the electron density below 1014 cm-3. The result indicates the poloidal location at high-field side near helical coils has a slightly higher temperature, i.e., 220 eV, compared to the temperature near separatrix X-point, i.e., 170 eV. |
