Problems solved by technology

The feedthrough seal obtained through the processing of the present invention firstly solves the problem that the existing feedthrough seal cannot be used in a high-vacuum operating environment, and at the same time solves the problem that the inner and outer conductors are not in the same axis during the brazing process of the traditional feedthrough seal

Embodiment Construction

[0016] A processing and welding process for a penetration seal, comprising the following steps:

[0017] (1) Process the Kovar structure 104 of the inner conductor 102 and the outer conductor 101 of the penetrating seal by using the machining center;

[0018] (2) Using ultrapure water to chemically clean the outer conductor 101, the conductor 102 and the ceramic window 103;

[0019] (3) Nickel-plating the surfaces of the outer conductor 101, conductor 102 and ceramic window 103, and heat treatment by means of vacuum heating and annealing;

[0020] (4) If there is no peeling phenomenon on the surface of the outer conductor 101, conductor 102 and ceramic window 103 after heat treatment, proceed to the next step; if peeling occurs on the surface of the outer conductor 101, conductor 102 and ceramic window 103 after heat treatment, then by controlling the annealing temperature and annealing cooling curve to control the peeling phenomenon, and then enter the next step;

Abstract

The invention relates to the technical field of particle accelerators, in particular to a feedthrough processing and welding process used for the technical field of particle accelerators. Novel feedthroughs which can adapt to the particle accelerators and need to run and operate under high vacuum conditions can be produced by means of the process, and customized production can be achieved according to customer demands.

Description

technical field [0001] The invention relates to the technical field of particle accelerators, in particular to a processing and welding process for a penetration seal in the technical field of particle accelerators. Background technique [0002] The feedthrough seal, also known as Feedthrough, is used to provide a channel for electricity, gas or fluid to be transmitted from the outside of the vacuum chamber to the inside of the vacuum chamber. Feedthrough must not only ensure the sealing of the vacuum, but also ensure the electrical isolation from the vacuum chamber . However, the existing Feedthrough is only suitable for low-vacuum operating environments, and cannot adapt to particle accelerators and other operating environments that require high vacuum degrees. There are problems such as insufficient vacuum degree and inability to ensure the concentricity of the outer conductor. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentio...
