Fermilab center renamed after late particle physicist Helen Edwards
Fermi National Accelerator Laboratory’s Integrated Engineering Research Center, which officially opened in January 2024, is now known as the Helen Edwards Engineering Center. The name was changed to honor the late particle physicist who led the design, construction, commissioning, and operation of the lab’s Tevatron accelerator and was part of the Water Resources Development Act signed by President Biden in December 2024, according to a Fermilab press release.

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.
