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 the GAMMA 10 central ECRH experiments, the electron heating estimated from the soft X-ray (SX) measurement was observed with any X-mode ratio. As increasing X-mode ratio from 0% to 100%, the SX power signal increased from about 2 times to about 3 times. And the Diamagnetic signal at the central cell (DMCC) increase is the maximum (+5%) with 100% X-mode. That is, 100% X-mode is the appropriate injecting polarization as expected. The DMCC decrease was observed except with 100% X-mode though electron heating was observed. And as decreasing X-mode ratio, the peak intensity of SX radial profile shifted from the center to the South and the asymmetric electron heating was observed. And as decreasing X-mode ratio, the peripheral ion loss seems to increase.
