There will be 4 targets that will be placed in the beam. Each sample of the selenium pellets had to be under 0.5g to meet waste restrictions. The 4 samples are as follows: one empty aluminum cylinder, one aluminum cylinder with only soil, one aluminum cylinder with a 50% ratio of soil to selenium, and one aluminum cylinder with a 10% ratio of soil to selenium. The selenium targets were prepared by measuring the mass of the sample, then putting a front nickel foil and a back nickel foil around the selenium pellets and wrapping the whole target in Kapton tape. The mass of an empty cylinder is 32.65g
