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.”

For the stellarator Uragan-2M, a glow discharge system for wall conditioning was developed and installed. The experiments were conducted in the range of discharge currents from 0.025 to 1 A and argon working gas pressures from 0.27 to 13.1 Pa. It is found that the measured current-voltage characteristics are similar to the discharge with a hollow cathode. In the optical spectrum of the glow discharge plasma, Ar lines of the excited atoms Ar I (Ar*) and ions Ar II (Ar+*) of the main argon gas, as well as the lines of excited hydrogen atoms H I (H*), are observed. The appearance of hydrogen is associated with the desorption of hydrogen from stainless steel because of the interaction of argon with the surface of the vacuum chamber (cathode). The radial profile of plasma density and electron temperature was measured using a movable triple probe. The maximum plasma density was 7.6 × 1014 m−3, and the plasma temperature was 4.6 eV.
