AMPeers has demonstrated STAR wires with record-high J_e of ~ 600 A/mm² at 4.2 K, 30 T corresponding to J_e of > 1,000 A/mm² at 4.2 K, 20 T using high current REBCO tape strands made using Advanced Metal Organic Chemical Vapor Deposition (MOCVD). Advanced MOCVD tapes exhibit more than 3x the critical current of commercial-grade REBCO tapes.

AMPeers has scaled up symmetric REBCO tapes with 18 – 20 µm thick substrate to 100 meters and STAR^® wires to over 60 meters. An 1.84 mm diameter, 61.5 meter STAR^® wire has been demonstrated with a I_c of 370A at 77 K. A 23 m long, 1.95 mm diameter STAR^® wire has been produced with a I_c of 482 A at 77 K.
