X-ray observations of Ne-like Xe and satellites from C-Mod tokamak plasmas
We discuss X-ray spectra in the wavelength range from 2.70 to 2.76 °A from xenon (Z = 54) in near neon-like charge states have been observed in Alcator C-Mod tokamak plasmas. The 3D (2p 6 - (2p 5 ) 3/2 3d 5/2 , 2720.4 m°A) and 3F (2p 6 - (2p 5 ) 1/2 3s 1/2 , 2729.0 m°A) transitions from neon-like Xe 44+ have been identified, along with nearby Na-, Mgand Al-like satellites. The intensity ratio of 3D to the Mg-like satellite near 2.74 °A increases strongly with electron temperature in the range from 3 to 4 keV.
