X-ray observations of ne-like xe and satellites from C-Mod tokamak plasmas

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 mA) and 3F (2p(6) - (2p(5))(1/2)3s(1/2), 2729.0 mA) transitions from neon-like Xe44+ have been identified, along with nearby Na-, Mg- and 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.
