Abstract

In this study, a detailed spatial measurements of 9 atomic barium species and 4 ionic species at various times of the discharge cycle are presented. This study addresses the spatially resolved density measurements of the ground state which was not accounted for in the study of Hook. Using the new technique, it was found out that Hook equation in the presence of large spatial gradients becomes invalid. This defect was called the 'lens effect' which is first reported in this experimental investigation. By understanding and minimizing the lens effect, increased measurements especially in the neighbourhood of the tube wall were obtained.
