Numerical simulations using an improved calculational scheme for ion charge state distribution and ion temperature evolution in an EBIT

Forskningsoutput: TidskriftsbidragArtikel i vetenskaplig tidskrift


A calculation scheme with significant modifications and improvements for determining the ionization balance and the ion temperature evolution in an electron beam ion trap (EBIT) is presented. The scheme is applied to thorium, tantalum and oxygen ions using a specific set of EBIT operating parameters. The results of the calculation are compared to experiment and previous calculations. Rates for the individual atomic processes in EBIT, in particular, single and multiple charge exchange processes are discussed. The time evolution of the ion temperatures for both thorium and its coolant oxygen are also given.
