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.

First astatine-labeled compound shipped in the U.S.
The Department of Energy’s National Isotope Development Center (NIDC) on March 31 announced the successful long-distance shipment in the United States of a biologically active compound labeled with the medical radioisotope astatine-211 (At-211). Because previous shipments have included only the “bare” isotope, the NIDC has described the development as “unleashing medical innovation.”

A diagnostic neutral beam (DNB) is used in the Tokamak Fusion Test Reactor (TFTR) to provide a time-modulated, spatially localized enhancement of the signal in the charge-exchange (CX) diagnostic. Two autonomous charge-exchange neutral analyzer (CENA) systems have been designed f or the TFTR. The first system measures the plasma ion temperature along as many as 12 vertical line-of-sight chords spaced approximately equidistantly across the torus minor diameter. The second system emphasizes the measurement of ion phenomena associated with neutral beam injection heating and has a fanlike field of view along six sightlines in the equatorial plane. The DNB is steerable in order to access the viewing field of either CENA system. The performance of the DNB is evaluated to determine the optimal beam parameters for active CX measurements. Using the optimal beam design parameters, the effectiveness of the neutral beam doping is examined for both CENA systems over the envisioned range of the plasma density and temperature in TFTR.
