発明の名称 (英語) METHOD FOR MANUFACTURING PURE NIOBIUM END GROUP COMPONENTS FOR SUPERCONDUCTING HIGH-FREQUENCY ACCELERATION CAVITY
発明の概要(英語) [Problem] To provide a method for manufacturing thick pure niobium end group components for a superconducting high-frequency acceleration cavity wherein conventional cutting processes and water jet processes are converted to pressing processes. [Solution] The method for manufacturing pure niobium end group components for a superconducting high-frequency acceleration cavity used in the acceleration of charged particles is characterized by: comprising (1) a shear cutting process that differs from precision blanking for forming a principal form while constraining thick pure niobium material by a binding jig with a fine clearance of 0.5% or less of the sheet thickness of the thick pure niobium material, and (2) a forging process differing from any of hot rolling, warm rolling, and cold rolling forging for forming a processed product while avoiding blue brittleness by low-temperature region temperature control of the principal form from room temperature to 200°C; and converting a cutting process and a water jet process for thick pure niobium end group components to pressing processes.
