论文摘要
我们发现了来自大型螺旋装置的核心等离子体的12条未知的可见发射线，并积累了高电荷的钨离子。该观察结果是通过我们的自制梯形光谱仪进行的，该光谱仪覆盖了450-715 nm的波长范围，波长分辨率为<0.05 nm，均为两条视线；一条线通过核心和边缘等离子体，另一线仅通过边缘等离子体。 These emission lines are attributed to highly charged tungsten ions because (1) they were observed only after a tungsten pellet was injected into the plasma, (2) they were observed only from the core plasma where the electron temperature is 1 keV, (3) they show line broadenings that are close to the Doppler widths of tungsten ions with 1 keV temperature and (4) the wavelengths of some of these emission线接近钨离子在25-28的电荷状态下的计算结果。
We found 12 unknown visible emission lines from the core plasma of large helical device with highly charged tungsten ions accumulated. The observation was made with our home-built echelle spectrometer, which covers the wavelength range of 450-715 nm with a wavelength resolution of<0.05 nm for two lines of sight; one line passes both the core and edge plasmas and the other passes only the edge plasma. These emission lines are attributed to highly charged tungsten ions because (1) they were observed only after a tungsten pellet was injected into the plasma, (2) they were observed only from the core plasma where the electron temperature is 1 keV, (3) they show line broadenings that are close to the Doppler widths of tungsten ions with 1 keV temperature and (4) the wavelengths of some of these emission lines are close to the calculation results for tungsten ions in the charge state of 25-28.
