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.”

When describing neutrons interacting with homogeneous media, Monte Carlo can generate a sequence of energies and flight directions without locating the positions of the collisions that produced them. If the spatial distribution of one of these collisions is then described analytically, unbiased direct samples of the neutron density can conveniently be obtained at specified positions and energies and at discretely sampled angles. Previous applications for plane sources in infinite media with real cross sections are here generalized for plane sources in slabs and point sources within infinite half spaces. A modified treatment for heterogeneous media is also formulated. These extensions to other geometries can provide not only additional calculational standards, but also theoretical results that could disagree with experimental facts only because of the assumed nuclear data.
