Description
Alternative materials are required in the SRF field to push the cavity performance limits. At Cornell, we investigate various A15 superconductor options that include Nb3Sn, V3Si, MgB2, and NbTiN thin films. We also explore different deposition approaches and post processes to optimize the material properties. In the workshop, we provide an overview of the ongoing progress at Cornell. Specifically, we discuss the electroplating and sputtering approaches to generate high quality Nb3Sn thin films via direct deposition or taking advantage of post annealing. We also report a passivation study on the MgB2 films. Lastly, we discuss the structural characterization on NbTiN films for S-I-S multilayer structures.
