Title:
超伝導加速空洞の製造方法
Document Type and Number:
Japanese Patent JP5595114
Kind Code:
B2
Abstract:
Provided is a method of manufacturing a superconducting accelerator cavity with which a support structure at the time of welding can be simplified and an inner surface of a product formed thereof can also be made smooth. In a method of manufacturing a superconducting accelerator cavity in which a plurality of half cells (15) having opening portions (equator portions (13) and iris portions (11)) at both ends thereof in an axial direction are placed one after another in the axial direction, contact portions (21) where the corresponding opening portions come into contact with each other are joined by welding, and thus, a superconducting accelerator cavity is manufactured, the half cells (15) to be joined are arranged so that the axial direction thereof extends in a vertical direction; and concave portions (25) that are concave towards an outer side are also formed at inner circumferential surfaces located below the contact portions (21) of the half cells (15) positioned at a bottom; and the contact portions (21) are joined from outside by penetration welding.
