Method to unfold the density distribution of any axially symmetric liner from radiographic data

Summary form only given. Since the outer liner layer where the instabilities develop consists of liquid and high density plasma phases, it is of great diagnostic interest to be able to unfold the radial density distribution of the bellows-like liner from the radiographic data. In this paper we propose a numerical method, coupled with a set of straight forward experimental calibrations, which will enable us to do so. This method is applicable in general provided that the liner has a good axial symmetry. The spatial resolution of the radiography are limited by the finite size of the X-ray source and also complicated by the scattered radiation. Detailed formulation of our method will be discussed together with these experimental complications.
