Research: I work in the technical division where they produce and test possible materials to be used in SRF cavities which are superconductors that accelerate particles within the particle accelerator that would further increase their efficiency by increasing its quality factor and thus decreasing the cost. My project is to test the durability of the new sample of Niobium with a Tin coating. My job is to test whether or not the coating could withstand the manufacturing process of the SRF cavities without cracking as well while it is in use at high and very low temperatures. I test this by using a tensile tester that measures both strain and stress . I also test the thermal conductivity of the samples with a PPMS ( Physical Property Measurement System ) to determine how heat flows in the material since we need to maintain the superconductor at 2K using liquid helium. These tests will determine whether or not Nb_3_Sn will be used in the future hoping that it increases efficiency
