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.”

Two types of neutral beam sources have been developed in order to measure plasma parameters on the Hanbit mirror device. The first source is a diagnostic neutral beam (DNB) which consists of a hydrogen neutral beam with a beam energy of 30 keV and a total beam current of ca. 1 A. The ion temperature profile can be determined by measuring directly the broadening of the Hα line emitted from hydrogen neutrals produced through the charge exchange recombination reaction with the DNB in the plasma. A fibre optic array detector, which works as an ideal notching filter, was developed to filter out the intense Hα line emitted from the cold hydrogen atoms in the plasma edge. The second source is a hyperthermal neutral beam (HNB) which consists of neutral particles with an energy of 1-100 eV. The HNB can be used to measure electron temperature and density profiles in the region between the core and the outer edge. This region cannot be covered either by Thomson scattering or by electrostatic probes. The feasibility of obtaining profiles of electron density and temperature by means of a helium HNB with a collisonal radiative equilibrium code has been performed.
