    Sam Posen is a graduate student working with Professor Matthias Liepe in Cornell's Superconducting Radiofrequency group. Sam is investigating an alloy of niobium and tin, Nb3Sn, as an alternative material for superconducting RF cavities, which are used in particle accelerators to provide energy to the beam. "All SRF cavities in accelerators now use niobium as the superconducting material," says Sam, "because it has great properties and, since it is an element we're working with, it is very easy to achieve uniform stoichiometry over the entire surface of a cavity. Compared to niobium, almost no development has gone into alternative materials. This means that there is a rich region of science waiting to be explored experimentally. How do small imperfections in the material affect RF currents when they are comparable in size to the superconducting wavefunction? Which theoretical predictions that have been made for the RF critical magnetic field in highly type-II superconductors are correct? These are some of the questions I plan to investigate." More ...
