Atomic dynamics during radiation induced solid-solid transitions

We propose to probe the beam induced dynamics in a α-quartz single crystal by means of X-ray photo correlation spectroscopy (XPCS). We expect an amorphization process analogue to that measured in the neutron irradiated crystalline samples. Furthermore, we will monitor the structure of the irradiated sample using an additional detector mounted near the sample stage. The experiment would provide a complete structural and dynamical analysis of the solid-solid transition pumped by the ionizing beam.
