Alessandro Marinoni: Returning to fusion’s D-turn

Alessandro Marinoni has continued to examine an innovative plasma shape, dubbed “negative triangularity,” extending previous research to configurations more compatible with the plasma environment of a reactor.

Candid-camera capture

MIT graduate student Aaron Rosenthal and colleagues from PPPL use a pinhole camera technique to answer questions about what is happening in the edge of hot plasmas confined in tokamaks.

Steering Fusion’s “D-turn”

PSFC research scientist Alessandro Marinoni researchers at the DIII-D National Fusion Facility have discovered promising evidence that reversing the conventional shape of the plasma in the tokamak chamber can create a more stable environment for fusion to occur, even under high pressure.


Juan Ruiz Ruiz: The Heat of the Matter

Ruiz is researching how to keep the plasma in a tokamak hot enough for fusion to take place. This is challenging because the hottest particles in the plasma, found in the core, leak towards the cooler areas at the edges, creating a plasma that will not be hot enough to sustain fusion. 


MIT fusion collaboration receives renewed funding

As part of an initiative to support the development of nuclear fusion as a future practical energy source, the U. S Department of Energy is renewing 3-year funding for two PSFC projects on the Wendelstein7-X (W7-X) stellarator at the Max Planck Institute for Plasma Physics in Greifswald, Germany.


Wright, Wukitch win Landau-Spitzer Award

The American Physical Society (APS) has recognized MIT Plasma Science and Fusion Center (PSFC) principal research scientists John Wright and Stephen Wukitch for their collaboration with Yevgen Kazikov and Jef Ongena of the Laboratory for Plasma Physics, Brussels, Belgium, with the Landau-Spitzer Award.


Cristina Rea: Taming fusion with machine learning

PSFC Postdoc Cristina Rea is developing a database to centralize information about disruptions in C-Mod, DIII-D and other tokamaks around the world. Through machine learning techniques to model and predict the progress of distruptions Rea hopes to find ways to mitigate the problem.


Rick Leccacorvi receives 2018 Infinite Mile Award

Mechanical design and fabrication specialist Rick Leccacorvi was honored with a 2018 Infinite Mile Award on May 23. His work designing experimental apparatus for physicists and students at the PSFC has received continued enthusiastic appreciation from his peers.


Bridging the gap between simulation and reality

Creely is using data from the Alcator C-Mod tokamak to validate simulations of fusion plasmas that could provide researchers with confidence that their simulations will accurately predict what will happen in a working fusion deviceand influence the design of future machines.
