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.”

A variety of shaped fill holes is needed in beryllium capsules for inertial confinement fusion experiments to allow for pyrolysis of the plastic (CH) mandrels, deuterium (D2) or deuterium-tritium gas fill, and fill tube attachments. The holes required include through-holes ranging in diameters from ~5 to 30 m and counterbores ranging in diameters from ~13 to 17 m with depths <37 m. These holes are laser drilled using a double-pulse nanosecond format. Hole diameter and depth can be controlled by altering pulse format, energy, and beam delivery optics. Furthermore, according to National Ignition Campaign specifications, there is a tight tolerance for perturbations on capsule surfaces, so we have developed a technique to eliminate material redeposition through the use of sacrificial foils stretched over the targeted areas.
