CFS Fusion Magnet Test Exceeds Expectations

Подробнее о видео

We’re one step closer to creating commercially relevant fusion energy. The strong performance of our Central Solenoid Model Coil (CSMC), an electromagnet prototype that MIT helped design, build, and test, proves out the second foundational magnet technology necessary to operate our first fusion machine, SPARC.

SPARC uses two types of magnets, those with steady electrical currents and those with pulsed electricity. The CSMC integrated years of research about how to build the pulsed-energy magnets, a successful sequel to the 2021 TFMC test of steady-state magnets..

The test was a huge win, giving us the confidence that these magnets can shoulder the load they’ll carry in SPARC. We’ve got the green light to ramp up manufacturing for the SPARC’s pulsed-power magnets.

In the long run, these magnets let us create smaller and therefore more economical successors to SPARC for generating electricity for the grid. CSMC accelerates us down the path to bringing clean, abundant fusion energy to the grid.

Watch as our team details the magnets and the importance of this milestone and the process of creating this technology.
