Description
Technical Field
The invention relates to the technical field of accelerators, in particular to an RFQ water supply system convenient for real-time monitoring and maintenance.
Background
A Radio Frequency Quadrupole (RFQ) accelerator is a high-current low-energy ion linear accelerator. Because the ion source can directly accelerate low-energy ions led out from the ion source and collect a plurality of functions of acceleration, longitudinal clustering, transverse focusing, matching and the like into one structure, the ion source can efficiently accelerate strong-current ion beams of dozens of milliamperes, hundreds of milliamperes and even ampere levels to about 7 MeV/mu. The radio frequency quadrupole field accelerator is used as a general front-stage accelerator of a low-energy strong-current accelerator, and is increasingly widely applied to large scientific devices such as a spallation neutron source, an accelerator driving clean nuclear energy system, a neutron and micro-neutron factory and the like, and application devices such as a small accelerator neutron source and the like. Conventional rf quadrupole accelerator configurations include four-wing and four-bar types, wherein the four-wing rf quadrupole is suitable for operation at higher frequencies, for high duty cycles and for high average rf power conditions. At present, the four-wing type radio frequency quadrupole field has become a commonly selected accelerating structure in the initial stage of the high current accelerator (starting from an ion source to the energy of several MeV).
When ions run in the radio frequency quadrupole field, the high-frequency electromagnetic field generates a strong heat effect in the cavity of the linear accelerator, so that the accelerated particles have high heat flux density and the heat load fluctuates continuously, and further the temperature of the cavity of the accelerator is increased and the inherent frequency of the accelerator is changed. Especially, the temperature and frequency of the end unit, the electrode and the coupling unit are changed most obviously, so that during the construction of the radio frequency quadrupole field accelerator, a corresponding water supply circulation system is generally configured for the engineering to cool the cavity of the accelerator. In theory, the heat load of four electrodes of each acceleration section is the largest, and the four electrodes are made of heat sensitive elements, the heat effect is the most obvious, the temperature rises the fastest, the part with the highest temperature of the cavity of the whole accelerator is the most urgent part needing cooling, therefore, in actual construction, some projects can distinguish and treat the water supply circulating system, because the projects consider that the cooling between different parts in the cavity of the accelerator is inconsistent and needs different cooling requirements and effects, the projects with a plurality of groups of different water supply circulating systems for realizing the cooling effect exist in the same cavity, not only is the construction difficult, large in maintenance cost and more important is difficult to realize real-time monitoring in practical significance.
For example, chinese patent application No. 2019104191053 discloses a water distribution system for a four-wing rf quadrupole accelerator cavity, which includes a left water distribution pipeline and a right water distribution pipeline disposed at both sides of the accelerator cavity, both the left water distribution pipeline and the right water distribution pipeline include a general water distribution pipeline and an electrode water distribution pipeline, the electrode water distribution pipeline includes an electrode water inlet main pipe, a plurality of electrode water inlet branch pipes, a plurality of electrode water return branch pipes, and an electrode water return main pipe, although the technical scheme is provided with the electrode water distribution pipeline specially used for cooling the electrodes, the four electrodes at both ends of each acceleration section of the accelerator cavity are cooled, so that the temperature between different parts in the accelerator cavity is maintained at the same temperature, thereby stabilizing the temperature and frequency in the accelerator cavity, and obtaining a strong ion beam with stable frequency from the accelerator cavity, but because of the four-section cavity partition design, meanwhile, the left water distribution pipeline and the right water distribution pipeline are arranged in a mode of being arranged in the same way, so that the water distribution of different return water branches is unbalanced, the design makes the process relatively complex, the construction cost is high, and the maintenance is inconvenient; in addition, the electrode backwater branch and the general backwater branch collect a plurality of primary backwater branches to secondary backwater branches with less quantity through a water separator, and the secondary backwater branches are provided with less quantity of temperature sensors and flow meters, so that the design is difficult to carry out real-time monitoring on the temperature and the flow of the branch water path in practical sense if the design is not matched with a powerful control system and a screen display system, and the situation of false alarm of signals can be caused probably; more importantly, in the technical scheme, the water supply system and the RFQ mounting bracket are mixed into a whole, so that the maintenance work of manual operation is not easy to implement.
