Abstract
Provided is a port member of a superconducting accelerating cavity, the entire size of which is reduced and which has enhanced working efficiency to achieve a lower manufacturing cost. In a pickup port () of a superconducting accelerating cavity, one end is joined by welding to a port portion () formed on a higher order mode coupler () which is provided at an end of a cavity body, while the other end is joined by flange coupling to a pickup antenna (). A port body () and a flange portion () are integrally formed of a niobium material having low purity or a niobium alloy containing a component other than niobium at a percentage lower than a prescribed percentage. The flange coupling is achieved with use of a quick coupling ().
