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.

EPA issues final rule regulating “forever chemicals”
The Environmental Protection Agency announced that it will issue a rule aimed at limiting public exposure to per- and polyfluoroalkyl substances (PFAS). The final rule will designate two widely used PFAS chemicals, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), also known as Superfund.
According to the EPA, both PFOA and PFOS meet the statutory criteria for designation as hazardous substances.

High density helicon plasma is produced by a 13.56 MHz rf discharge under an IGBT-pulsed expanding and strong magnetic field, where the compact solenoid (inner diameter of 10 cm and 616 turn) is used for the formation of the magnetic field. The solenoid current is pulsed by the IGBT device with a pulse width of 20-40 msec. The solenoid current and the resultant magnetic field strength are proportional to the charging voltage to the capacitor. In the presently used solenoid and circuit, the maximum current and the resultant field strength are about 56 A and 3 kGauss, respectively. For the rf power of about 700 W, the high density plasma of about 4 × 1012 cm-3 is achieved. Above the field strength of about 1.6 kGauss, the source plasma density is constant, while the downstream density increases due to the suppression of the radial loss of the plasma particles.
