The invention discloses production equipment for isotopes. The equipment comprises a linear accelerator and a target system corresponding to the linear accelerator; the linear accelerator comprises anormal-temperature front-end accelerator, a plurality of identical acceleration units or a plurality of acceleration modules connected in series with one another and arranged behind the normal-temperature front-end accelerator, and tail-end leading-out bunch wires led out from the output end of one acceleration unit located at the tail end; each acceleration module is formed by coupling of a plurality of acceleration units connected in series with one another; and the tail-end leading-out bunch wires are used to output proton beams used by the target system, and the target system is used for production of the isotopes. The production equipment for the isotopes provided by the invention can meet requirements of production of multiple isotopes, improve the production capacity and efficiencyof the isotopes, and save the equipment manufacturing costs; and on the basis, the acceleration units are further modularized and the quantity of leading-out bunch wires is increased, so that one production equipment for the isotopes provided by the invention can meet the requirements of simultaneous production of the multiple isotopes, and the production efficiency of the isotopes is improved byseveral times.

Description

technical field [0001] The invention relates to isotope production equipment and belongs to the technical field of isotope production equipment. Background technique [0002] The discovery of naturalness more than a hundred years ago has caused a great revolution in human beings' updating of the universe and knowledge. In today's world, radioactive elements and radioisotopes are used in various fields such as medicine, industry, agriculture and scientific research. In many applications, radioisotopes have no substitutes so far. Radioactive isotopes are used in almost all countries of the world, 50 of which have facilities for isotope production and separation. [0003] Large quantities of radioisotopes are typically produced using research reactors and cyclotrons. Isotope production facilities also include nuclear power plants, isotope separation facilities, and general accelerators not specialized in isotopes. There are 600 research reactors in operation worldwide, but o...

AI Technical Summary

Problems solved by technology

[0006] (1) The extraction beam intensity is low and the isotope production efficiency is low

[0007] The cyclotron is used for isotope production, and the intensity of the extracted beam is low, and the highest level is only on the order of hundreds of μA. This is mainly because the cyclotron is a weakly focused structure. Once the beam intensity increases, the space charge force of the beam will be very significant, and the entire The efficiency of the cyclotron will decrease. The efficiency of a good cyclotron is close to 90%, and the efficiency of some cyclotrons is even less than 30%. The loss of the beam will bring obvious thermal problems and radiation activation problems. In order to reduce the radiation dose to human acceptable level, thick concrete is also needed to shield the entire accelerator

On the other hand, it is also difficult to extract the cyclotron beam, and the increase of the beam intensity will further increase the heat and activation problems caused by the extraction.

[0008] (2) The energy of the extracted beam is fixed, and the isotope production capacity is single

However, this method will generate a large amount of radiation, which will easily cause the activation of the device and increase the cost of shielding. Moreover, the quality of the beam after scattering is poor, most of the beam will be lost, and the passing efficiency is low.
