Adjusting device for superconductive circular accelerator lead-out zone magnet channel

Abstract

The invention discloses an adjusting device for a superconductive circular accelerator lead-out zone magnet channel. The adjusting device comprises a first adjusting mechanism, a second adjusting mechanism and a separation seal box, wherein each of the first adjusting mechanism and the second adjusting mechanism comprises a first outer tube, a second outer tube and a third outer tube; a screw rod is arranged in each of the second outer tubes of the first adjusting mechanism and the second adjusting mechanism, and one end of each screw rod is connected with a mobile flange via a ball bearing while the other end drives the first outer tubes of the first adjusting mechanism and the second adjusting mechanism to move forward in a rotating manner; one end of each of the third outer tubes of the first adjusting mechanism and the second adjusting mechanism is welded in the separation seal box, a drive rod is arranged in each third outer tube, one end of each drive rod is connected with a push rod in a screwed manner, and the mobile flange is connected with the push rod in a welded manner. Via the adjusting device disclosed in the invention, safe and reliable seal of the accelerator can be ensured while vacuum environment of the accelerator is not damaged, the adjusting device is simple in structure, requirements for adjusting precision can be met without complex motor drive, and low cost and high reliability can be realized.

Description

technical field [0001] The invention relates to an adjusting device for an accelerator lead-out area, in particular to an adjusting device for a magnetic channel in the lead-out area of ​​a superconducting cyclotron in an ultra-high vacuum environment. Background technique [0002] The superconducting cyclotron is an ultra-high vacuum container that accelerates protons / heavy ions through electromagnetic fields, and extracts the proton beams accelerated to a certain energy out of the accelerator. The magnetic channel in the extraction area is the key component for extracting protons / heavy ions, which can be focused and extracting protons / heavy ions; its position and angle have a great influence on the efficiency of extracting protons / heavy ions, so it is very important to fine-tune its position and angle according to the actual needs of the project. [0003] At present, there are two known ways to adjust the magnetic channel in the lead-out area of ​​the accelerator. One is t...

Problems solved by technology

[0003] At present, there are two known ways to adjust the magnetic channel in the lead-out area of ​​the accelerator. One is to destroy the vacuum environment and open the accelerator cavity for internal adjustment. This method will destroy the vacuum environment, and the uncertainty of the number of magnetic channel adjustments may lead to opening the cavity The number of times is high, which is not conducive to the safety and reliability of the vacuum seal; another method is to place the adjustment device outside the accelerator, using a very complicated control and mechanical system, and achieve fine-tuning of the position and angle of the magnetic channel in the lead-out area by controlling the motor. purpose, the system is complex and costly
