Manufacturing second-generation high-temperature superconducting tape with REBCO (rare-earth barium copper oxide) chemistry for use in fusion reactor magnets, power transmission cables and specialty applications.
Delivering 8,000+ km to fusion companies; Zama factory operational since 2024.

Ion-beam-assisted deposition creates a textured template that aligns the superconductor crystal lattice.
Pulsed laser deposition deposits the REBCO layer, which becomes superconducting when cooled below 92 K (above the boiling point of liquid nitrogen).
Magnetron sputtering applies silver, then electroplating adds copper to protect the superconductor and improve current carrying.
