High-Field Plug Coil

The burner's end-cap magnet that plugs the mirror.

Cyclic fatigue

The burner's plug coils are its highest-field magnets, reaching 26.49 T at the ion end, creating the high-field throat and helping build the ambipolar potential that confines the central-cell plasma. Their cyclic fatigue at full field is the burner's binding magnet gate.
