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.

DON'T MISS!

Steve Shanabruch, Chicago illustrator

1-2 p.m.
Saturday, April 18
Harold Washington Library Center, 400 S. State St.

The event is free, but registration is required; only a few seats are remaining. Block Club Arts & Culture Editor Gwen Ihnat will moderate the discussion.

"Chicago artist Steve Shanabruch is illustrating and documenting the city — one neighborhood print and font at a time.

"Since 2012, when Shanabruch launched his Chicago Neighborhoods series, he’s been creating vintage-style posters commemorating different parts of Chicago. For each piece, he’ll pick a landmark to highlight a neighborhood — like a hot-dog stand in Norwood Park, the Yale Building in Englewood, Frank Lloyd Wright’s Foster House in West Pullman and the Mars candy factory in Galewood."

This hidden Novato gem comes alive in winter. A short, kid-friendly trail leads to a seasonal waterfall that's rushing right now. Located at the end of Fairway Drive, it's the perfect family adventure when the rain rolls in. #visitnovato

No he didn’t, Libby. His written remarks referred to Greenland as a “piece of ice” because that’s what it is.

You’re the only one mixing anything up here.

It is with profound sadness that we share the passing of Bobby Weir. We send him off the way he sent so many of us on our way: with a farewell that isn’t an ending, but a blessing.  A reward for a life worth livin'. https://t.co/2qdBbh80v1
