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 theory for determining the ratio of the prompt to the delayed neutronic response, Wp/Wd, of a self-powered vanadium detector using methods of stochastic processes are described. Experimental data are also presented. The technique makes use of the inherent reactor noise; it is based upon cross correlating the fluctuating detector current signals from the actual vanadium detector and from a (purely prompt responding) cobalt self-powered detector, both of which are located in a power reactor close to each other. Both the analysis in the time domain and in the frequency domain were used to extract the ratio Wp/Wd. The measurements were performed at the Halden Boiling Water Reactor at 7 MW(th) and the ratio Wp/Wd of a commercial vanadium detector has been determined to be (6.5 ± 0.35)%. The technique described offers several advantages over the commonly used transient measuring method.
