Abstract
It is well known that when a silica optical fiber is irradiated by neutrons or heavy ions, there is an attenuation of the transmission of the signal which is due to the creation of specific radiation damage. We have been able to show the creation of alpha radiation damage in borosilicate glass and glass used for radioactive waste confining in studying their properties of thermostimulated luminescence after high alpha irradiation. We have been able to correlate these radiation damages with interatomic bond break which implies oxygen. To extend this research to all silica optical fiber, the thermostimulated luminescence mechanisms of vitreous silica have been analysed. To exalt its properties in thermostimulated luminescence it has been doped with aluminium. Then, the creation of alpha radiation damage has been searched in this vitreous silica doped with aluminium. The next step of the study is an extending of this method to detect the effect of neutronic or heavy ions irradiation on vitreous silica samples which constitutes the basic material of optical fiber used in nuclear harsh environment.
