Abstract

The invention discloses a continuous wave radio frequency four-level accelerator water cooling system. A water cooling pipeline is arranged in an air foil. The air foil is in a structure of a sharding. The water cooling pipeline is in a plate-box snake shape and is arranged on an abutting joint surface of the sharding of the air foil. A welding flux groove is arranged around the water cooling pipeline. Meanwhile, the invention discloses a manufacturing method for the water cooling system. The continuous wave radio frequency four-level accelerator water cooling system and the manufacturing method of the continuous wave radio frequency four-level accelerator water cooling system have the advantages that compared with a through straight line water cooling pipeline, the size of the snake-shaped water cooling pipeline is increased, the water cooling is thorough and efficiency is high. The problem of heat dissipation of a radio frequency four-level accelerator operating under the continuous wave is solved. Heat dissipation performance is greatly improved, frequency of the radio frequency four-level accelerator can be precisely controlled and stability of a beam current is guaranteed, thus acceleration performance is enabled to be effectively stabilized and improved. Tightness when the water cooling pipeline is operated for a long time in the inner portion of the air foil in an electron beam welding mode in a manufacturing process is guaranteed and high purity of oxygen-free copper materials is guaranteed. Integrity and solidity of the sharding air foil and structural reliability and working stability of the continuous wave radio frequency four-level accelerator are strengthened by brazing.

Description

technical field [0001] The invention relates to a water cooling system and a manufacturing method thereof, in particular to a continuous wave radio frequency quadruple accelerator water cooling system and a manufacturing method thereof. Background technique [0002] Radio Frequency Quadrupole (RFQ) accelerator is a high-efficiency linear acceleration for various low-speed charged particles from protons to uranium ions, which can simultaneously use the radial component of its radio frequency electric field to focus and the longitudinal component to accelerate. structure. It integrates multiple functions such as matching, shaping, beamforming and accelerating. It can directly accept the low-speed strong current continuous beam drawn from the ion source, and accelerate the particles to Energy of a few MeV per nucleon. In addition, due to its small size and convenient use, the RFQ accelerator is of great research and practical value whether it is used as an injection device fo...

Problems solved by technology

attached figure 1 It is a cross-sectional view of the fins of a pulsed radio frequency quadruple accelerator, showing the water cooling system. The water cooling system of a room temperature radio frequency quadruple accelerator is generally composed of one or several transparent linear water cooling pipes on the fins. This structure will cause the following two problems : 1. The heat dissipation of the fins is uneven, and the place close to the water-cooling pipeline is cooled first; 2. In the continuous wave state, the temperature of the fins and the entire RF quadruple accelerator cannot be effectively and accurately controlled, and the resulting application difficulty is its Cooling issues and frequency drift due to temperature changes

If only by increasing the number of water-cooling pipelines to ensure heat dissipation, it may not be able to meet the cooling requirements, and may cause processing difficulties and subsequent system water leakage problems, and complicate peripheral supporting equipment
