ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

A prototype negative ion source is in development toward the giant negative ion source for the China Fusion Engineering Test Reactor neutral beam injection system at the Institute of Plasma Physics, Chinese Academy of Sciences. The multiaperture and multichannel grids are the most challengeable during the construction of the prototype negative ion source. The research and development activities for the grid manufacturing method were carried out and divided into detailed design, implementation, and testing phases. Based on a special manufacturing process involving the vacuum brazing technique, some prototype grids were produced. Two prototypes have similar structures to the extraction grid of the prototype negative ion source except for the reduced number of cooling channels. A testing campaign (including dimension inspection, leak tests, thermal imaging tests, and magnetic tests) was carried out. The results demonstrate that the manufacturing process and construction technology can meet the requirements of the extraction grid and can promote the construction of other grids or components having a similar structure.
