Description

Target station hot cell system for isotope production and operation flow thereof Technical Field The invention relates to the technical field of isotope production hot chambers, in particular to a target station hot chamber system for isotope production and an operation flow thereof. Background The hot cell is a shielded enclosure for high-activity testing and operation, and is primarily used to prevent leakage of radioactive materials and to protect operators from radiation injury. The interior of the hot chamber is generally provided with remote operating devices such as a master manipulator and a slave manipulator, and the like, which are used for carrying out corresponding process operation on the high-radioactivity substances. With the development of modern medicine and nuclear medicine technology, medical radioisotopes play an increasingly important role in disease diagnosis and clinical treatment. However, the mass production capacity of alpha radionuclides is not effectively improved, and the alpha radionuclides become a main constraint factor for large-scale popularization in the field of alpha targeted therapy. Breaking through the high-power accelerator irradiation production technology is the key to solving the problem of supply of rare medical isotopes. In high power beam irradiation production, beam heat power needs to be distributed to a larger area to meet the requirement of target cooling. The proton beam corresponding to a few milliamperes has strong current, and tens of hundreds of target pieces are required to be reasonably arranged in space, so that the heat exchange efficiency is improved as much as possible. Chinese patent number 202510261285.2 discloses a target device for isotope production.

Therefore, it is needed to develop a hot cell system of a target station with higher operation efficiency, so that the hot cell system of the target station can be matched with the target device, so that a large number of target pieces can be irradiated by using high-energy and high-current beam current at the same time, the production efficiency of isotopes is greatly improved, and breakthrough of the irradiation production technology of a high-power accelerator is realized.
