The key elements in the technology of 2G HTS wires manufacturing at SuperOx Japan LLC rely on the Electropolished 60 mkm Hastelloy substrate, Magnetron MgO-IBAD texturing process, PLD deposition of the GdBaCuO superconductor.
Currently SuperOx Japan is capable of producing 2G HTS taped of up to 600 m length with the critical current of 500A. The mass production of the commercial quality 2G HTS tapes is aimed at 250-300m length and Ic = 400A for 12 mm tape. The manufactured superconducting tapes have excellent homogeneity of the critical current Ic along the tape length.
The architecture of the superconducting wires developed by SuperOx Japan is shown in the following figure. The combination of magnetron and PLD methods is very flexible for efficient production.
