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.

A new method to diagnose the degree of electron degeneracy in compressed fuel for fast-ignition inertial confinement fusion is proposed. We focus on 4.44-MeV -rays emitted in the reaction 9Be(,n)12C governed by fusion-produced energetic alpha-particles in a laser-imploded DT fuel pellet admixed with a small amount of 9B. In this case the compressed fuel pellet is not subjected to any heating laser pulse. We have evaluated the probability P-Be that the + 9Be reaction occurs during the slowing down of -particle. It is found that the reaction probability depends strongly on the degeneracy parameter , which is defined as the ratio of electron temperature to the Fermi energy. We show the possibility of diagnosing the electron degeneracy from the P-Be - diagram by detecting the 4.44-MeV -quanta and DT neutrons emitted from the dense core plasma.
