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.

Taking shape: Fusion energy ecosystems built with public-private partnerships
It’s possible to describe fusion in simple terms: heat and squeeze small atoms to get abundant clean energy. But there’s nothing simple about getting fusion ready for the grid.
Private developers, national lab and university researchers, suppliers, and end users working toward that goal are developing a range of complex technologies to reach fusion temperatures and pressures, confounded by science and technology gaps linked to plasma behavior; materials, diagnostics, and electronics for extreme environments; fuel cycle sustainability; and economics.

In the GAMMA10 tandem mirror, waves with ion cyclotron range of frequency (ICRF) have been used for plasma production and heating. Magneto Hydro Dynamic (MHD) stability is kept with the anchor cells which have minimum-B configuration. In a typical discharge, plasmas in the anchor cell are heated with ICRF waves excited by Type-III antennas installed in the central cell. In order to produce high performance plasma, anchor heating should be enhanced. Double-Arc Type (DAT) antennas are installed in both east and west anchor cells. In this study, direct heating experiments in both east and west anchor cells with DAT antenna are performed. DAT antenna is driven with the different frequency from Type-III antenna and driven with the same frequency. In the same frequency case, the phase difference between both antennas can be changed. In both the different and the same frequency cases, the increase of the line density is clearly observed in the central and anchor cells. Stronger effects are observed in the east anchor than in the west anchor.
