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 deuterium-deuterium neutron generator device based on the 2.45-GHz electron cyclotron resonance technique has been designed. The device achieves a neutron yield of 5 × 108 n/s supplied by the ion source with a beam current of 5 mA. The device is intended for use in radiation modification, isotope production, prompt gamma neutron activation analysis, and boron neutron capture therapy studies. In this work, we study the effects of stainless steel, glass, and aluminum (Al) chamber linings with boron nitride (BN) and glass front plates on both the ion source–induced beam quality and the neutron source yield. The results show that the combination of an Al chamber liner with a BN front plate liner increases current and neutron yield by three to four times compared to other combinations. Stable Al2O3 films generated on the Al surface in air, as confirmed by X-ray diffraction pattern analysis, have a high secondary electron emission coefficient and low wall recombination coefficient, which contributes to the generation of D+ ions in the chamber. As a result, the ion source current and neutron generator yield are improved.
