The SRF group at Cornell is dedicated to the study of the basic phenomena and application of superconductivity in high frequency conditions. The first use of SRF cavities in a high energy physics accelerator was in 1975 at Cornell's 10 GeV synchrotron. From the beginning, and even now, Cornell's SRF group has been a world-wide leader in the field of RF superconductivity and its application to high energy accelerators and synchrotron light sources.

The SRF Laboratory occupies a significant portion of Newman Laboratory on the Cornell campus. Laboratories include extensive clean-rooms for cavity construction. Once constructed, SRF cavities go through multiple stages of high-pressure rinsing, electropolishing, and high-temperature baking, all on-site at Newman Lab. After cleaning, cavities are then tested under different loaded conditions, in single-cell and multi-cell arrangements.
