High-Field Plug Coil
The burner's end-cap magnet that plugs the mirror.
- Peak field
- 26.49 T
- Gate
- 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.
Common questions
Why is the plug coil the burner's most critical magnet?
It reaches the burner's peak field, 26.49 T, to build the ambipolar potential that confines the central plasma. Its cyclic fatigue at full field is the burner's single binding magnet gate.
How is that fatigue gate closed?
By a powered REBCO test coil taken through many energise cycles at full field. A single cycle is well within limits; it is the repeated cycling that must be demonstrated, and Kronos names it openly rather than assuming it.
