Space charge formation and defects creation in irradiated ceramics

During the irradiation of a dielectric material, different types of defects are produced depending on the irradiating conditions (either with ions or electrons) and on the nature of the material. Also, by changing the energy of the ion beams, the ratio of the ionization-induced defects versus the nu...

Description
Summary:During the irradiation of a dielectric material, different types of defects are produced depending on the irradiating conditions (either with ions or electrons) and on the nature of the material. Also, by changing the energy of the ion beams, the ratio of the ionization-induced defects versus the nuclear-collision induced defects can be changed. After irradiation, different kinds of stable defects are thus produced and a space-charge can be established. The aim of the present study is to correlate the space-charge buildup and defects formation in insulating materials under charged particle beams. For this purpose, we perform on-line defect characterization by spectroscopic measurements together with on-line bulk space-charge density measurements with the pressure wave propagation (PWP) method. This extended abstract presents the aim of our experimental study, and describes the principle and the set-up of the PWP method.
