Description

Technical Field

[0001] The utility model relates to the technical field of accelerators, in particular to a tooling mounting device for an accelerating tube in a BNCT accelerator. Background Art

[0002] The earlier accelerating tubes used in BNCT accelerators (boron neutron capture therapy, BNCT) are often bonded. In some accelerating tube designs that are not convenient to use other connection processes, the bonding process design is also considered. The bonded accelerating tube is made of glass rings and stainless steel electrodes, which are bonded by glue. This method has good sealing at room temperature. Due to the certain pressure difference between the inside and outside of the accelerating tube and the reasons for the assembly and use of the accelerating tube, the accelerating tube must also have sufficient mechanical strength. When considering complex load conditions, high operating temperatures and reliability factors, usually only ceramic / metal welding connection process can be selected.

[0003] Before welding, all parts of the accelerating tube must be assembled. In the traditional assembly process, only some parts of the accelerating tube can be accurately positioned. The accelerating tube is welded by combining multiple layers of parts. The overall coaxiality and centering of the accelerating tube are extremely important in the subsequent use. Parts that are not accurately positioned will result in large differences in coaxiality and centering that cannot meet actual use requirements, resulting in low production efficiency and high production costs.
