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.”

Particle control is an essential requirement for long-pulse operation. Besides steady-state particle exhaust, the complementary key element is particle fueling. Three fueling methods are currently used in Tore Supra: conventional gas puffing, supersonic molecular beam injection, and pellet injection. In addition to a technical description of the corresponding systems, this paper presents an overview of different studies characterizing these methods in terms of fueling efficiency and ability to fuel long discharges or to obtain high-density plasmas with no confinement degradation. An analysis of the interaction between the plasma and the pellet or supersonic beam is also given, including the physics of the homogenization of the deposited particles in the background plasma (importance of the edge cooling and of the [nabla]B-induced displacement) or the transport-induced modification for deep-matter penetration (triggering of an improved confinement phase or, conversely, of a sawtooth crash when a pellet crosses the q = 1 surface).
