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.”

To improve the efficiency of gas chromatography for hydrogen isotope separation near room temperature, feasibility of new columns was examined for H-D and H-D-T mixture gases. One kind of the column was the mixture of Pd-Pt alloy and Cu powders as the previous study. But special attention was paid for preparing the separation column; Pd-Pt alloy particles below 200 mesh was mixed with copper powder of 150–200 mesh and packed into a loading tube of stainless steel as uniform as possible. The separation for H-D mixture gases could be remarkably improved by this column even at temperatures around 300 K. This column also could separate tritium as T2 from H-D-T mixture gas containing only 0.13 % T. The other column was prepared by Pd-Pt alloy supported by porous SiC powder for economical use of the expensive alloy. Although this column gave similar separation chromatograms, the separation efficiency was still insufficient and further studies are required.
