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
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

ANS webinar to focus on low-dose radiation risk
Join ANS on Thursday, January 21, at noon (ET) for a Q&A with an expert panel as they discuss how to communicate about the risk of low-dose radiation. “Talking About Low-dose Radiation Risk” is a free members-only event that serves as a follow-up to the “Risky Business” President’s Session that took place during the ANS Virtual Winter Meeting last November. The session will take a deeper dive into the many questions generated from the thought-provoking discussion.
Register now to attend the webinar.

In order to generate a toroidal field in field-reversed configuration (FRC) plasma, a poloidal current drive by axial neutral beam injection (NBI) is investigated analytically and numerically. Species of neutral beam particle are hydrogen and helium. Feasibility for two types of injection geometry, injection along the geometric axis and to near the separatrix, is tested. Since all beam ions are lost directly through the device end, more than 12-kA beam current is needed to improve electron confinement near the separatrix. On the other hand, it is found that low energy (about 200 eV) beam ions can be confined for injection to near the separatrix. Present calculation of the beam ion orbit shows possibility of poloidal current drive and toroidal field generation by axial NBI into an FRC plasma.
