Installing SPARC's third superstrong TF magnet #SPARC #Magnets #FusionEnergy

So how do you confine a superhot, 100M°C fusion plasma? With superstrong magnets, of course. 🧲

We've now installed three of the 18 toroidal field (TF) magnets needed for our SPARC fusion demonstration machine. TF magnets are one of the three major magnet types we'll use in SPARC (the others being the poloidal field and central solenoid magnets) to corral the plasma once the machine is operating. Because plasma is made up of charged particles, it responds to a magnetic field. It's a technique refined over dozens of earlier tokamaks built around the world that manage this highly energetic cloud of particles that's hotter than the center of the sun.
