REBCO Coil Winding Model
Coils are built by stacking and winding REBCO tapes into turns, then into pancakes, insulated and clamped against huge forces.
From tape to magnet
A single REBCO tape carries a useful but limited current. To make a magnet, many tapes are combined and wound into turns, and many turns are stacked into a coil. The winding pattern, how the tapes are laid, insulated, and supported, determines the field the coil produces and whether it survives the forces that field creates.
Building up the coil
- Tapes are stacked or cabled to carry the required total current.
- Turns are wound in a defined pattern, often as flat pancake sections stacked together.
- Insulation, or in some designs deliberately reduced insulation, is placed between turns.
- The whole coil is clamped in structure to react the magnetic forces.
Insulated versus no-insulation
A design choice in REBCO coils is how much to insulate between turns. Fully insulated coils force all current along the intended path; no-insulation coils let current cross between turns, which can protect the coil during a quench by spreading current away from a hot spot, at the cost of slower response. This trade-off is one of the active engineering questions in high-field REBCO magnets.
In the model
The winding structure is signed-in detail. A selected coil can be expanded to show its turn and pancake layout, letting you see how the conductor path builds up the field. In the public tier the coil is shown as a solid magnet with its field callout, sufficient to understand its role without the fine winding detail.
Forces and cooling
Wound coils must be held against enormous forces and kept cold. See the magnet support structure, the quench protection, and the cryogenic cooling.
