Abstract

The invention relates to the technical field of a new manufacturing process of hydrogen furnace brazing of a four-airfoil-type radio frequency quadrupole-field accelerator cavity, in particular to a four-airfoil-shape radio frequency quadrupole-field accelerator cavity hydrogen furnace brazing method. According to the method, during brazing, brazed parts are assembled and fixed so that mutual positions of the parts and welding gaps required during brazing can be guaranteed. A brazing clamp is used in the whole part brazing processes of fixing, assembling, entering a furnace, brazing and discharging out of the furnace, and whether the clamp is reasonable and practical influences brazing quality directly. After a brazing mode of a new fastening structure is adopted, the success rate of cavity welding is greatly increased, the resistance on the surface of the welded cavity is small, conductivity performance is good, stability is good, the appearance size is small, the shape is little changed, vacuum indexes are good, and the overall performance of the four-airfoil-shape radio frequency quadrupole-field (RFQ) accelerator cavity is improved.

Description

Technical field [0001] The invention relates to the technical field of a new hydrogen furnace brazing manufacturing process for a four-wing radio frequency quadrupole field accelerator cavity, in particular to a hydrogen furnace brazing method for a four-wing radio frequency quadrupole field accelerator cavity. Background technique [0002] The radio frequency quadrupole (RFQ) accelerator cavity is the core component of the RFQ linear accelerator, and its manufacturing level is one of the key factors affecting the performance parameters of the accelerator. Through the wave-shaped modulation lines on the four wings, a longitudinal electric field is generated on the beam center line of the cavity, thereby accelerating the beam. Its stability and reliability are very important to the accelerator. Therefore, whether the RFQ can be guaranteed through a good welding process The welding quality of the accelerator cavity is related to the stability and consistency of the cavity electric ...
