Maria Gatu Johnson (born 1978) [1] is a Swedish-American plasma physicist whose research involves the use of neutron spectrometry to study inertial confinement fusion and stellar nucleosynthesis. She works at the Massachusetts Institute of Technology as a principal research scientist in the MIT Plasma Science and Fusion Center. [2]

Education and career

Gatu Johnson earned a master's degree in engineering physics from Uppsala University in Sweden in 2003, and completed a Ph.D. in applied nuclear physics there in 2010. [3] Her work there involved the application of neutron spectrometry to the Joint European Torus, a magnetic confinement fusion experiment in England. [4]

She was a postdoctoral researcher at the MIT Plasma Science and Fusion Center from 2010 to 2013, before becoming a permanent member of the research staff there. [3] In 2023 she was promoted to principal research scientist. [2] At the Plasma Science and Fusion Center, she has been in charge of the Magnetic Recoil Neutron Spectrometer (MRS) beginning in 2013. [5]

Recognition

Gatu Johnson was the 2019 recipient of the Katherine E. Weimer Award of the American Physical Society (APS), given biennially to recognize early-career research excellence by a female plasma physicist. [6] She is a recipient of the 2022 National Nuclear Security Administration Secretary's Honor Award, [7] and of the 2023 Department of Energy Secretary's Achievement Award. [8]

In 2022, the Burning Plasma Team of the National Ignition Facility, including Gatu Johnson, received the John Dawson Award for Excellence in Plasma Physics Research of the APS, given "for the first laboratory demonstration of a burning deuterium-tritium plasma where alpha heating dominates the plasma energetics". [5] [9]

She was named a Fellow of the American Physical Society in 2023, after a nomination from the APS Division of Plasma Physics, "for pioneering efforts in the cross-cut field of plasma-nuclear science and for groundbreaking studies of macroscopic plasma flows in Inertial Confinement Fusion implosions". [10]

Fusion power is a proposed form of power generation that would generate electricity by using heat from nuclear fusion reactions. In a fusion process, two lighter atomic nuclei combine to form a heavier nucleus, while releasing energy. Devices designed to harness this energy are known as fusion reactors. Research into fusion reactors began in the 1940s, but as of 2023, no device has reached net power.

The Levitated Dipole Experiment (LDX) was an experiment investigating the generation of fusion power using the concept of a levitated dipole. The device was the first of its kind to test the levitated dipole concept and was funded by the US Department of Energy. The machine was also part of a collaboration between the MIT Plasma Science and Fusion Center and Columbia University, where another (non-levitated) dipole experiment, the Collisionless Terrella Experiment (CTX), was located.

John Myrick Dawson was an American computational physicist and the father of plasma-based acceleration techniques. Dawson earned his degrees in physics from the University of Maryland, College Park: a B.S. in 1952 and Ph.D. in 1957. His thesis "Distortion of Atoms and Molecules in Dense Media" was prepared under the guidance of Zaka Slawsky.

Fusion ignition is the point at which a nuclear fusion reaction becomes self-sustaining. This occurs when the energy being given off by the reaction heats the fuel mass more rapidly than it cools. In other words, fusion ignition is the point at which the increasing self-heating of the nuclear fusion removes the need for external heating. This is quantified by the Lawson criterion. Ignition can also be defined by the fusion energy gain factor.
