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.

Unlike tokamaks, where the neutral beam shine through is rarely an issue, open magnetic systems with neutral beam injection oftentimes suffer from incomplete beam capture, which necessitates the handling of the shine through power load and beam particle recycling. The cathodic arc gettering, which provides high evaporation rate coupled with a fast time response, is a powerful and versatile technique for depositing clean getter films in vacuum. A compact neutral beam dump utilizing the titanium arc gettering was developed for a field-reversed configuration plasma sustained by 1 MW, 20–40 keV neutral hydrogen beams. The beam dump is capable of handling large, pulsed gas loads, has a high sorption capacity, and is robust and reliable. The beam recycling coefficient, measured under the beam particle flux density of 5 × 1017 H/(cm2s) sustained for 3–10 ms, is ~0.7. The use of the beam dump allows to reduce the recycling of the shine through neutral beam by factor of 3–5, as well as to improve the vacuum conditions in the machine.
