Developing of superconductive niobium cavities for accelerating devices
Abstract
The analyses of important characteristics of high purity niobium were done. The results of a study of structure and mechanical properties of welding joints, superconducting characteristics of the material after joining of welded components of superconducting radio frequency cavities are presented. The manufacturing technology of SRF niobium cavity using liquid impact forging, electron beam welding and chemical polishing was developed. The paper also describes the results of testing of the SRF 1.3 GHz single-cell niobium cavity manufactured in the PTI NAS of Belarus.
