New Optical Research Data Have Been Reported by Researchers at Massachusetts Institute of Technology (Validation of x-ray line ratios for electron temperature determination in tokamak plasmas)

By a News Reporter-Staff News Editor at Physics Week -- A new study on Optical Research is now available. According to news reporting from Cambridge, Massachusetts, by VerticalNews journalists, research stated, "X-ray imaging crystal spectroscopy (XICS) has been implemented on magnetic confinement fusion devices as a novel means of measuring local plasma temperature, impurity density, and flow profiles. At Alcator C-Mod, XICS allows for spatially-resolved, high spectral resolution measurements between 0.3 and 0.4 nm, enabling detailed analysis of He-like argon x-ray emission."

The news correspondents obtained a quote from the research from the Massachusetts Institute of Technology, "Electron temperatures in the range of 0.5 keV = 3 satellites, specifically the wavelength range of 3.9440 angstrom

According to the news reporters, the research concluded: "The electron temperature can be determined from the relation to the line ratio, x, as T-e[keV] = 0.1552x(-0.7781) with 0.0223 < x< 0.2449."
