Photoionization of Cl II induced by synchrotron radiation

POSTER

Abstract

The photoionization of Chlorine ions is a fundamental process of interest in several plasma environments. For instance, in FC reactors, negative halogen ions beams are candidates for the injectors. In astrophysics Cl was detected in Io's ionosphere and is used as hydrogen abundance markers. The photoionization of Cl$^{+}$ was measured with a resolution of 20 meV in the photon energy range of 19.5 eV to 27.5 eV. The experiment was carried out in the 10.0.1 end station of the Advanced Light Source. Structures corresponding to Rydberg series are identified. Absolute cross sections were measured.
