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.”

CH capsules, produced through glow discharge plasma coating, routinely suffer from surface defects including domes with gradually sloping sides and dust particles with sharp edges. Surface defects seed instabilities during implosion experiments on the National Ignition Facility and lead to radial jets, which increase mixing at the center of the implosion hindering the shell compression. Avoiding such defects requires characterizing the entire shell surface. In addition, the global position of the defects must be recorded in order to coordinate shot results with the initial surface perturbations. Further work was done to enable side-by-side comparison with optically acquired images to aid in capsule surface inspection throughout the capsule production process.
