Title: Electronic excitation damage by swift ions to SiO2: New experimental evidences

Abstract:The recent results obtained at CMAM on the color centers generated in SiO2 (crystalline and amorphous) by swift ions are reviewed. By using Br ions with energies in the range from 2 to 40 MeV, it has been possible to separate the contributions associated to elastic collisions and electronic excitations. The data on kinetics, coloring efficiencies and thresholding are analysed with a didactical perspective. The role of crystallinity is described. Finally, the possibility of either an excitonic or a thermal scission mechanism is discussed.
