Division Spotlight
Accelerator Applications
The division was organized to promote the advancement of knowledge of the use of particle accelerator technologies for nuclear and other applications. It focuses on production of neutrons and other particles, utilization of these particles for scientific or industrial purposes, such as the production or destruction of radionuclides significant to energy, medicine, defense or other endeavors, as well as imaging and diagnostics.

High-temperature plumbing and advanced reactors
The use of nuclear fission power and its role in impacting climate change is hotly debated. Fission advocates argue that short-term solutions would involve the rapid deployment of Gen III+ nuclear reactors, like Vogtle-3 and -4, while long-term climate change impact would rely on the creation and implementation of Gen IV reactors, “inherently safe” reactors that use passive laws of physics and chemistry rather than active controls such as valves and pumps to operate safely. While Gen IV reactors vary in many ways, one thing unites nearly all of them: the use of exotic, high-temperature coolants. These fluids, like molten salts and liquid metals, can enable reactor engineers to design much safer nuclear reactors—ultimately because the boiling point of each fluid is extremely high. Fluids that remain liquid over large temperature ranges can provide good heat transfer through many demanding conditions, all with minimal pressurization. Although the most apparent use for these fluids is advanced fission power, they have the potential to be applied to other power generation sources such as fusion, thermal storage, solar, or high-temperature process heat.1–3

The principle of the traveling wave direct energy converter is introduced. The mechanism is understood as a combination of the traveling wave tube and the linear accelerator. Hardware of the traveling wave direct energy converter is also introduced. It becomes obvious that the applied engineering and materials are conventional. The traveling wave direct energy converter is studied numerically. Self-excitation in a transmission circuit has been verified and optimized geometry is obtained with one-dimensional calculations. For a case of ARTEMIS, 69.8 % of overall conversion efficiency was obtained. Experiments on traveling wave direct converter have been carried out. Self-excitation of a traveling wave has been observed. As conclusions, a traveling wave direct energy converter appears promising to apply to an open magnetic system with D-3He fusion fuels.
