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 genetic algorithm (GA)-based method has been developed to analyze Charge-eXchange Recombination Spectroscopy (CXRS) data and provide in-between shot evaluation of the ion temperature profile during Tore Supra experiments. The GA method proposed here proves to be fast and fairly accurate, even when analyzing low signal-to-noise data. Simulations using theoretical signals suggest that the ion temperature and the plasma rotation velocity are expected to be determined with a precision better than 10% for a noise level up to 5% of the spectrum peak. The good agreement with the commonly used KS4FIT code when analyzing CXRS experimental data - typically within 30% for ion temperature measurements - confirms the efficiency of such an analysis tool.
