Division Spotlight
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

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 order to decrease the wall absorption of hohlraums during the laser-matter interaction encountered in X-ray indirect-drive inertial confinement fusion, a thick layer of depleted uranium (DU) and gold alloy can be deposited on the inner surface of the hohlraums. Such a coating can be achieved by sputtering simultaneously DU and gold directly into the hohlraums. This technique is called "moulding PVD." In order to validate the moulding PVD technique, Au/Mo cocktail layers were deposited on glass substrates by simultaneous multitarget sputtering. Molybdenum is used for deposition of cocktail alloys since it shows the same sputtering yields as uranium. Au/Mo cocktail layers can be easily grown on glass substrates at any desired composition and controlled thickness by optimizing the deposition parameters. A major issue of DU deposition is its rapid delamination in contact with water, air, or hydrogen. To protect the DU/Au alloy, a thin coating of dense gold is sputtered on the DU alloy. Dense and low-stress gold thin films deposited on glass substrates have been achieved by optimization of processing parameters. The effect of such a coating has been quantified thanks to the study of praseodymium oxidation (which is more sensitive to delamination than DU). A gold coating thickness of 0.2 m thoroughly decreases the oxidation rate of praseodymium in contact with air.
