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.

Recently, the EAST W/Cu divertor components, including the ITER-like monoblock W/Cu units and flat-type W/Cu units, have been developed by Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP) in collaboration with Advanced Technology and Materials Co., Ltd. (AT&M). To detect the bonding quality in these multiple layer geometry W/Cu plasma-facing components (PFCs) at each step of their manufacture, special nondestructive testing techniques have been researched and developed. For monoblock W/Cu PFCs, the bonding at both W-Cu and Cu-CuCrZr interfaces was qualified by spiral ultrasonic testing (UT) with a focus probe, which was inserted into the CuCrZr tube with a flexible driving tube. Artificial defects with defined size have been measured by UT and compared with the results of high heat flux testing (HHFT). The HHFT demonstrated that the monoblock W/Cu mock-up qualified by this UT has withstood 1000 cycles of heat load at 10 MW/m2. The bonding quality of flat-type W/Cu mock-ups has also been inspected by the usual water-gap UT. The results from HHFT at 5 MW/m2 demonstrated that the present UT was unreliable for the quality control of the flat-type W/Cu PFCs.
