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.”

Current capsules used at the National Ignition Facility utilize a single-shell design comprised of a single ablator material. Although single-shell designs are currently the standard design, they suffer from several physics disadvantages, such as sensitivity to asymmetries and instabilities. The double shell is a proposed design utilizing a high-Z inner metal shell with a low-Z outer shell that is intended to mitigate the issues associated with typical single-shell designs.
Electroplating is one method that can be utilized to fabricate high-Z metal shells. Au is one particular material that can be electroplated with high density and uniformity. Capsule fill tube assemblies (CFTAs) built from these Au shells have passed all cryogenic leak tests. The shells have a low native surface roughness and are free of voids. Au shells have been successfully fabricated, characterized, and built into CFTAs.
