Abstract
A connector for use in an ultra-high vacuum system that has a metal conduit section with a first hardness, a metal fitting member with a second hardness greater than the first hardness of the conduit section, and a metallic reaction-inhibiting barrier positioned between the conduit section and the fitting member to sealingly attach the conduit section and fitting member together. The metal conduit section has a first end, a second end, and a flow path between the first and second ends. The metal fitting member has a rear face proximate to the second end of the conduit section, a front face facing away from the rear face, and an opening between the front and rear faces aligned with the flow path of the conduit section. The reaction-inhibiting member also has an aperture aligned with the flow path of the conduit section and the opening of the fitting member. The reaction-inhibiting member is selected from a group of metals that will substantially inhibit metallic and chemical interaction between the conduit section and the fitting member. Accordingly, the reaction-inhibiting barrier prevents the joint between the metal conduit section and the metal fitting member from deteriorating and causing leaks under ultra-high vacuum and temperature cycling conditions.
