Experimenters get access to NSUF facilities for irradiation effects studies
The Department of Energy’s Office of Nuclear Energy announced the recipients of “first call” 2025 Nuclear Science User Facilities (NSUF) Rapid Turnaround Experiment (RTE) awards on June 26. The 23 proposals selected from industry, national laboratories, and universities will receive a total of about $1.4 million. While each project is led by a different principal investigator, some call the same organization home. A total of 17 companies, labs, and universities are represented.

The complexity of Compact Stellarator (CS) coils made from brittle A15 SC alloys results in a challenging design. Three options of manufacturing the ARIES-CS coils are discussed. The first two options use high performance Nb3Sn superconductor, one with the wind-and-react method, the second with react-and-wind. The magnet protection design philosophies are different for the two winding methods. Wind-and-react uses high conductor current with external dump, while react-and-wind uses low conductor current with internal dump. The use of non-uniform internal quench is explored as a means to minimizing the requirements for internal dump for the case of react-and-wind. Cooling of the superconductor is also fundamentally different in the two cases, as the hydraulic path of the react-and-wind option requires low velocity He in a sheathed Rutherford-like cable, cooled by a heat exchanger in accessible regions. In the third design option, HTS superconductors are deposited directly on the structure, minimizing conductor movement. Coil protection techniques will be described.
