Figure 4. Effect temperature and atmosphere on damage from an X-ray dose of 2.9 GGy. From left to right, nano-XRF damage scan, nano-XRF probe scan, µ-FTIR, AFM and optical images for samples measured at (A) room temperature and nitrogen obtained by a nitrogen flow and (B) cryogenic temperature and nitrogen obtained using a cold nitrogen flow. (C) Attenuation in the iodine content, (D) µ-FTIR intensity and (E) AFM depth profiles for the different conditions.
