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.

Recent R&D of an edge Thomson scattering system for ITER (International Thermonuclear Experimental Reactor) are reviewed. We have designed a diagnostic laser system (5 J, 100 Hz) based on JT-60U diagnostic laser design (7.46J, 50Hz). New laser oscillator has been developed, and prototype amplifier has been assembled for ITER. Regarding a collection optics in a port plug, improvement of previous design has been carrying out. As for spectrometers, a new technique of Fourier transform spectrometer for Thomson scattering has been considered in addition to a filter polychromator.
