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.”

Magnetic diagnostics are essential for the operation and understanding of a magnetic fusion device. Magnetic data are used in real time to measure and control the current, shape, and position of the discharge; the thermal energy of the plasma; the confining magnetic field; and the currents in the magnet coils. Equilibrium reconstructions based on magnetic data yield the magnetic geometry of the plasma, providing the coordinates for interpretation of all other diagnostic measurements. Magnetic measurements also provide input for the analysis and feedback control of magnetohydrodynamic (MHD) instabilities. This review focuses on the inductive loops and Hall effect probes that are used in nearly all present devices. We describe the principles of magnetic diagnostics and discuss issues related to their practical implementation. The interpretation of magnetic measurements for equilibrium reconstruction and for identification of MHD instabilities are summarized. Magnetic diagnostics based on inductive measurements are well understood in both implementation and interpretation and are expected to meet the needs of ITER. However, the challenges presented by future steady-state burning plasma experiments may require the development of other techniques. The prospects for addressing these challenges are reviewed, in particular, the status of possible approaches to long-pulse magnetic measurements.
