The two experiments described above were made of the same materials in very similar conditions. They show similar behavior with some differences in detail. The first experiment showed an initial increase in Ni 2+ concentration that stabilized and remained nearly constant for the remainder of the experiment. The concentration of Ni metal increased drastically after 2 hours and then decreased towards the end. This suggests that very small pieces of foil were transported through the beam. The second experiment showed a relatively small and basically constant concentration of Ni 2+ with occasional spikes in the Ni metal signal. The explanation for the lower and more constant Ni 2+ concentration and more chaotic Ni metal concentration in the second experiment lies in the difference in the external conditions. The second experiment maintained a significantly higher temperature which contributed to the metallic grains moving more quickly through the melt. Furthermore, the X-ray beam was placed farther from the foil in the second experiment causing lower concentrations and smaller pieces of Ni metal to reach the beam.
