Abstract

The method of using two laser produced plasmas, one acting as background continuum radiation source, the other as absorbing medium, for obtaining the absorption spectra and for measuring the photoionization cross-sections of low-Z ionic species is described. The basic principles of the experiment are discussed. The advantages of some technical solutions, like the use of stigmatic technique in VUV and XUV spectral regions, the use of detecting system using photodiode arrays, and the constrained deconvolution procedure adopted in data processing, are emphasized.
