EUV spectra from N-shell ions of Gd, Dy and W



Deirdre Kilbane, John D. Gillaspy, Yuri Ralchenko, Joseph Reader, G. O'Sullivan


Measurements of extreme ultraviolet radiation from gadolinium, dysprosium and tungsten ions with an open n=4 shell were performed at the National Institute of Standards and Technology. The ions were produced and confined in an electron beam ion trap and the spectra were recorded with a flat-field grazingincidence spectrometer in the wavelength range 3-17 nm. These data are useful for the development of future lithography sources and for diagnostics of hot plasmas in fusion devices.
