Secondary electron, 1H−, 2H− images and the 2H−/1H− ratio for three separate regions of interest (ROIs) showing the total counts summed over 10 image planes for ROIs 1 & 2 and 5 image planes for ROI 3. ROIs 1 and 2 are from the Zy-4 sample and ROI 3 is from the 48.3 day Zy-2 sample. ROIs 1 and 2 were implanted with 5.7 × 1017 ions/cm2 prior to imaging and imaged with currents of 1.79 pA and 1.75 pA respectively, a dwell time of 5000 μs/pixel and 256 × 256 pixels over a 30 μm raster size. ROI 3 was implanted with 3 × 1017 ions/cm2 prior to imaging and imaged with a current of 1.57 pA, a dwell time of 5000 μs/pixel and 256 × 256 pixels over a 30 μm raster size.
