Turning neutrons into fusion fuel

“One of the things that you get good at while at MIT,” says PSFC research scientist Sara Ferry, “is being able to start from nothing on a particular system or skill and knowing how to approach it in a way that’s effective.”

On Sunday, September 5, 2021, a large-bore, high temperature superconducting magnet designed and built by CFS and MIT reached a field of 20 tesla. It paves the way to building SPARC and commercializing fusion energy. These are highlights from the Live-Streamed 20 Tesla HTS Magnet Demo Event

VIDEO: Unlocking SPARC: HTS Magnet for Commercial Fusion Applications

An animation of how the high temperature superconducting (HTS) fusion magnet built by MIT's Plasma Science and Fusion Center (PSFC) and Commonwealth Fusion Systems (CFS)was tested. Reaching a field of 20 tesla, it is the most powerful superconducting magnet in the world and a key technology in SPARC, a compact, high-field tokamak that will produce net energy from fusion.

On Sept. 5, 2021, for the first time, a large high-temperature superconducting electromagnet was ramped up to a field strength of 20 tesla, the most powerful magnetic field of its kind ever created on Earth. That successful demonstration by the PSFC and CFS helps resolve the greatest uncertainty in the quest to build the world’s first fusion power plant that can produce more power than it consumes.

After overseeing three years of research and development, Brian LaBombard is ready to test a toroidal field model coil (TFMC), a prototype for those that will be used in the new fusion experiment, SPARC.

Wired for Success

MIT engineer, Vinny Fry is preparing to help test SPARC’s Toroidal Field Magnet Coil (TFMC), a scaled prototype for the HTS magnets that will surround the tokamak’s toroidal vacuum chamber to confine the plasma.

On course to create a fusion power plant

Since taking on course 22.63 (Principles of Fusion Engineering) over a decade ago Prof. Dennis Whyte has moved away from standard lectures, prodding the class to work collectively on  “real world” issues. The course has been instrumental in guiding the real future of fusion at the PSFC.


Keeping an eye on the fusion future

"When I actually got into the depths of fusion, seeing what the PSFC was doing - nothing ever compared,” says graduate student Dan Korsun.

Pushing the envelope with fusion magnets

Postdoctoral associate David Fischer's research focuses on observing ways irradiation damages the thin high-temperature superconductor tapes in the design of ARC, a fusion pilot plant concept.



Validating the physics behind SPARC

This series of papers provides a high level of confidence in the plasma physics and the performance predictions for SPARC. No unexpected impediments or surprises have shown up, and the remaining challenges appear to be manageable. This sets a solid basis for the device’s operation once constructed, according to Martin Greenwald, Deputy Director of MIT PSFC.

Heating by Cooling

As a graduate student Pablo Rodriguez-Fernandez (PhD’19) became intrigued by a fusion research mystery that had remained unsolved for 20 years. His novel observations and subsequent modeling helped provide the answer, earning him the 2019 Del Favero Thesis Prize.

For Green Energy, MIT Aims To Build 'A Star On Earth'

The future of fusion energy is right around the corner. You'll find it off Massachusetts Avenue, on Albany Street in Cambridge. It's on the campus of the Massachusetts Institute of Technology, in an old, low-rise, brown brick building once owned by Nabisco.
