Experimental Ionization Rate Coefficients of Aluminum and Silicon Ions
Abstract
Aluminium and silicon atoms have been introduced into a well diagnosed theta-pinch discharge by CO2-laser driven ablation from solid targets. The time histories of spectral lines from several ionization stages of these impurities produced in the hot transient pinch plasma are interpreted in terms of effective ionization rate coefficients. The validity of the method is discussed and a comparison of the results is made with semiempirical and theoretical approaches.
