Keith Burrell

from Wikipedia, the free encyclopedia

Keith H. Burrell (born April 13, 1947 in Santa Monica ) is an American plasma physicist .

Burrell studied physics at Stanford University with a bachelor's degree in 1968 and at Caltech with a master's degree in 1970 and a doctorate in 1975. He then worked at General Atomics in fusion research with tokamaks , especially the DIII-D tokamak from General Atomics. Before that, he did research at the ISX-A and B tokamak at Oak Ridge National Laboratory .

He played an important role in researching the H-mode in magnetically confined fusion plasmas (H for high confinement), which was discovered at the Asdex in 1982, and the transport mechanisms behind it, in particular the suppression of turbulence through the formation of shear currents. Burrell was involved in the discovery of the quiet H-mode ( quiescent H-mode ) on DIII-D in 1999, which has the advantages of H-modes, but no edge instabilities (Edge Localized Modes, ELM). Burrell also developed methods for plasma diagnostics.

In 2001 he received the Excellence in Plasma Physics Award from the American Physical Society . In 2018, he received the James Clerk Maxwell Prize in Plasma Physics for frontier research, including significant experimental advances and diagnostic development that established the connection between plasma shear flux and turbulent transport, resulting in improved confinement configurations of magnetized plasmas by reducing turbulent transport Shear flows (laudatory speech). He is a Fellow of the American Physical Society (1985) and the Institute of Physics .
