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.

Countering the nuclear workforce shortage narrative
James Chamberlain, director of the Nuclear, Utilities, and Energy Sector at Rullion, has declared that the nuclear industry will not have workforce challenges going forward. “It’s time to challenge the scarcity narrative,” he wrote in a recent online article. “Nuclear isn't short of talent; it’s short of imagination in how it attracts, trains, and supports the workforce of the future.”

The angular intensity profile of a single beamlet is expressed as a sum of a main Gaussian and a bump-on-the-tail representing the optical aberration. Transmission of a total beam comprised of a large number of beamlets is then analytically derived. By an iterative matching of the calculated transmissions to the measured transmissions through at least two downstream openings, the parameters that describe the single beamlet angular profile are determined. Some of the neutral beam injectors employed for heating fusion plasmas are characterized by this modeling. Also presented is an improved algorithm for calculating the intensity distribution at a downstream plane.
