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.”

Using the Total Absorption Method, the neutron multiplications in beryllium have been measured. A deionized water sphere with outer radius of 75 cm and a polyethylene sphere with outer radius of 69 cm were used as the total neutron absorbers. Neutron distributions in the spheres were measured using 235U fission chambers. The relative and the efficiency-determined methods were compared. Important sources of experimental errors were detailly analyzed. 4 groups of neutron multiplications in beryllium up to 14.85 cm thick for two total absorbers and two methods of measurement have been obtained and agreement among them is satisfactory. Measured results have been compared with ANISN calculations using data from ENDF/B-IV. It is shown that the differences between calculations and experiments are up to 15%.
