Measurements of electron temperature in x-ray heated plasmas
Abstract
Experimental study is presented of an electron temperature in an intense soft-x-ray heated plasma through extreme ultraviolet spectroscopy. Temperatures obtained from time integrated x-ray line and continuum emissions were found to be Te=53Ix(1013 W/cm2)0.29(eV) for Al plasma over the range of intensities of 1012 to 6×1012 W/cm2. The intensity scaling of temperature is compared with an analytical model and is found to agree well with this model.
