Superconducting radiofrequency (SRF) technology is being used in discovery science programs and basic research and it holds the potential for several applications that have a direct impact on society. The advantage of superconducting cavities over those made of normal-conducting metal is their ability to store large amounts of energy with much lower dissipation. The direction of future SRF technology is the development of high-performance superconducting radio frequency particle accelerators that deliver consistent performance with economically sustainable operation. So far bulk niobium is the material of choice for the fabrication of SRF cavities and recent advances in processing techniques improved the performance of these structures, although the fundamental physics behind these processes hasn’t been fully understood yet. The performance of these cavities are linked to the metallurgical state of niobium during fabrication and processing steps that greatly affect the superconducting properties in the microwave frequency range. In this talk, I will present the current status of cavities processing techniques, Nb materials specification and future directions in order to develop high performance SRF cavities.
