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 prototype negative ion source is in development toward the giant negative ion source for the China Fusion Engineering Test Reactor neutral beam injection system at the Institute of Plasma Physics, Chinese Academy of Sciences. The multiaperture and multichannel grids are the most challengeable during the construction of the prototype negative ion source. The research and development activities for the grid manufacturing method were carried out and divided into detailed design, implementation, and testing phases. Based on a special manufacturing process involving the vacuum brazing technique, some prototype grids were produced. Two prototypes have similar structures to the extraction grid of the prototype negative ion source except for the reduced number of cooling channels. A testing campaign (including dimension inspection, leak tests, thermal imaging tests, and magnetic tests) was carried out. The results demonstrate that the manufacturing process and construction technology can meet the requirements of the extraction grid and can promote the construction of other grids or components having a similar structure.
