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 fabrication of three multilayer Omega-scale capsule designs with combinations of materials such as beryllium, silicon, tungsten, and copper were evaluated as part of the fabrication and delivery process. These opaque capsule designs presented characterization challenges in that nominal optical characterization techniques for Omega-scale designs were not sufficient to fully characterize the capsules. Alternate techniques such as X-ray fluorescence, radiography, scanning electron microscopy, and spectroscopy needed to be utilized in order to characterize these capsule designs. Additionally, the permeability of each material varies; therefore, each capsule design required a different approach to fill the capsule for the experiment. Three techniques were used to deliver gas-filled capsules to the experimental teams: (a) filling through the drill hole, sealing with glue under pressure, and minimizing the glue mass using laser ablation; (b) attaching a capsule fill tube assembly into the drill hole; and (c) gas permeation through the wall. The issues encountered with these techniques and their solutions are presented.
