Remembering ANS member Gil Brown
Brown
The nuclear community is mourning the loss of Gilbert Brown, who passed away on July 11 at the age of 77 following a battle with cancer.
Brown, an American Nuclear Society Fellow and an ANS member for nearly 50 years, joined the faculty at Lowell Technological Institute—now the University of Massachusetts–Lowell—in 1973 and remained there for the rest of his career. He eventually became director of the UMass Lowell nuclear engineering program. After his retirement, he remained an emeritus professor at the university.
Sukesh Aghara, chair of the Nuclear Engineering Department Heads Organization, noted in an email to NEDHO members and others that “Gil was a relentless advocate for nuclear energy and a deeply respected member of our professional community. He was also a kind and generous friend—and one of the reasons I ended up at UMass Lowell. He served the university with great dedication. . . . Within NEDHO, Gil was a steady presence and served for many years as our treasurer. His contributions to nuclear engineering education and to this community will be dearly missed.”

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.
