Abstract :
A short review of Al-related point deflects and their radiation effects is presented. These defects exhibit spectroscopic signals which are monitored by a variety of experimental techniques. This discussion is useful to prospective researchers in the area of precision quartz resonators for frequency control in aerospace applications. Irradiation of quartz crystals at 77 K before and after irradiation at 300 K coupled with sweeping can be used for estimating the role of various point defects for their contribution in estimating the frequency offsets in quartz crystals in a radiation environment.
