X-ray Observations of Ne-like Xe and Satellites from C-Mod Tokamak Plasmas

Abstract

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 Xe^{44+} 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.
