The Burner's End Cell

The plug-and-expander assembly that confines the plasma and recovers its energy.

End-loss energy

Each end of the burner holds a high-field plug (26.49 T), the ambipolar potential it builds, and an expander feeding the direct converter. The end cell is where the burner's hardest physics — plugging — and its cleverest engineering — direct conversion — live.

It is the technical heart of the tandem mirror.
