Laser-Produced Plasma Spectroscopy of Medium to High-Z Elements in the 2 to 9 nm Spectral Region

Abstract

SynopsisMuch effort has gone into the development of plasmas as sources of radiation in the 2 to 9 nm region in recent times with particular interests in the “water window” region (2.3 to 4.4 nm) and the 6.X nm region. Plasmas were formed on a range of targets of medium to high atomic number (Z) elements using Nd:YAG lasers with various illumination parameters. Spectra were recorded using a 0.25 m grazing-incidence spectrograph and spectral analysis was carried out with the aid of Hartree-Fock with configuration interaction calculations using the Cowan suite of codes [1].
