Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 ＲＦ空洞共振器の結合部において、確実な真 空シール性と適正なＲＦコンタクト面圧及び剛性の高い 締結力を得ることができるＲＦ空洞共振器結合方法を提 供する。 【構成】 結合しようとする空洞２ａ，２ｂの端縁面の 全周に、内周側からフラットなコンタクト面３ａ，３ ｂ，少し凹んだ狭溝部４ａ，４ｂ，より多く凹んだ広溝 部５ａ，５ｂを形成しておく。そしてコンタクト面３ ａ，３ｂ同士を突合わせてＲＦコンタクトを行い、狭溝 部４ａ，４ｂにそれぞれダイヤフラム６ａ，６ｂを取付 けて互いの外縁同士に全周連続溶接７を施して真空シー ルを行い、更に広溝部５ａ，５ｂ同士間に周上複数個の タブ８を差渡して両端縁に溶接９を施して結合剛性及び コンタクト圧力を得る。 (57) [Abstract] [PROBLEMS] To provide an RF cavity resonator coupling method capable of obtaining a reliable vacuum sealing property, an appropriate RF contact surface pressure, and a fastening force with high rigidity in a coupling portion of an RF cavity resonator. . [Structure] The contact surfaces 3a, 3 which are flat from the inner peripheral side along the entire circumference of the edge surfaces of the cavities 2a, 2b to be coupled b, narrow groove portions 4a, 4b slightly recessed, and wide groove portions 5a, 5b recessed more. And contact surface 3 a and 3b are abutted against each other for RF contact, diaphragms 6a and 6b are attached to the narrow groove portions 4a and 4b, respectively, and continuous welding 7 is applied to the outer edges of each other to perform vacuum sealing. A plurality of tabs 8 are provided on the circumference between the 5b's and welds 9 are applied to both end edges to obtain coupling rigidity and contact pressure.
