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.

Eisenhower’s “Atoms for Peace” at 70
Seventy years ago to the day, President Dwight D. Eisenhower gave his historic address to the United Nations General Assembly in New York City. (See December 2023 Nuclear News's “Leaders” column to read the reflections of Kathryn Huff, the Department of Energy’s assistant secretary for nuclear energy, on the speech’s anniversary.)

Four different variations of doped, planar targets were fabricated using multilayer glow discharge polymerization for the foil thickness campaign at the Extended Performance Facility at the University of Rochester. The planar film targets consisted of from one to four layers of CH, CHGe, and CHSi. The composition of Ge and Si was controlled by the flow of dopant gas (either tetramethyl germane or tetramethyl silane) and measured with X-ray florescence. After laser cutting the 200 × 900 × 80-µm film targets out of the larger film, the targets were released from the substrate.
Coating nonuniformity when using an inductively coupled discharge device can be a challenge. We improved the uniformity by rotating the substrate. Film thickness was measured with a chromatic confocal sensor system. Thickness measurements were fit to a Gaussian function, which smoothed the thickness data set and allowed accurate interpolation of thickness measurements.
A challenge for freestanding, planar glow discharge polymer films is intrinsic stress in the coating. Prior to coating the final targets, the coating stress for various deposition parameters was measured. A series of runs with CH, CHGe, and CHSi were coated on thin silicon wafers. The wafers were characterized for bending before and after coating with a stylus profilometer to determine the coating stress using the Stony equation. In general, higher chamber operating pressures resulted in lower stress coatings.
