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.
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.

A more open future for nuclear research
A growing number of institutional, national, and funder mandates are requiring researchers to make their published work immediately publicly accessible, through either open repositories or open access (OA) publications. In addition, both private and public funders are developing policies, such as those from the Office of Science and Technology Policy and the European Commission, that ask researchers to make publicly available at the time of publication as much of their underlying data and other materials as possible. These, combined with movement in the scientific community toward embracing open science principles (seen, for example, in the dramatic rise of preprint servers like arXiv), demonstrate a need for a different kind of publishing outlet.

The design of an Advanced Large Volume Surface Plasma Source (LV SPS) for Neutral Beam Injectors is presented and discussed. The LV SPS will be assembled from a set of modules. Every module consists of a plasma generator with an RF saddle antenna injecting plasma and hyperthermal atoms into the expander chamber. The plasma electrode with multi-slit extraction system and localized magnetic filter is attached to the bottom flange of the expander chamber. The plasma will be generated by an RF discharge using a saddle antenna in an optimized longitudinal magnetic field. This type of discharge is very efficient for dense plasma generation. The magnetic field is used to suppress plasma diffusion to the wall, improve the efficiency of plasma generation and decrease the thermal flux to the plasma generator wall. The expanded flux of ions and hyperthermal atoms bombards uniformly the plasma electrodes of the extraction system and produces an intense beam of negative ions. With improved cooling, the average discharge power can be increased significantly above that of any existing SPS. With smaller slit emission apertures, it is possible to suppress H- stripping after extraction. These conditions are promising for reliable production of higher emission current density up to ~40–50 mA/cm2 with corresponding decrease of SPS dimensions and cost.
