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.
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.

To produce the laser targets needed for laser plasma experiments, the CEA target department uses different mechanical machining techniques and develops methods that are consistent with the target requirements in terms of quality, timing, and cost.
Combining these aims involves several challenges. First, laser experiments need a wide range of target geometries with common points: reduced dimensions (millimetric range) and thin walls (micrometric range), as well as very strict dimensional and geometric specifications. According to these requirements, the target specifications demand the machining of different kinds of materials from metals (aluminum, copper, and gold) to polymers and low-density foams.
In this context, the versatility of the machining processes is the key issue. These challenges necessitate the development and upgrading of machining techniques and methods as well as optimizing the engineering design to use the full potential of these techniques. In this presentation, three main machining processes are developed and illustrated: adaptations of machine tools for planar targets (by the flycutting method) and for machining complex shapes (combined milling and turning), the development of the original process to produce a baffle hohlraum, and the parametric optimizations of machining tantalum aerogel.
