Films of Mo3Re to Improve the Performance of Existing Superconducting Radiofrequency Accelerator Cavities

Improving the performance of existing superconducting radiofrequency cavities is one approach to improving the capabilities of existing accelerator facilities. By coating existing SRF cavities with Mo3Re, one could realize reduced coat of cryogenics and/or higher accelerating gradients. Alameda Applied Sciences Corp proposes to develop a thin film coating method to produce Mo3Re thin film superconductors for SRF cavities based upon niobium. AASC will deposit Mo3Re films on Nb coupons and correlate growth conditions with SRF properties. Commercial Applications and Other Benefits: Thousands of niobium accelerating cavities are used in specialized research accelerators. Improving the performance of these cavities is the first step toward realizing a commercial particle accelerator that utilizes SRF technology.
