“…Second-generation REBa 2 Cu 3 O 7−δ ((REBCO), RE=rare earth) high temperature superconducting (HTS) tapes, also called coated conductors (CCs), have been studied by many researchers of the world because of its excellent property of high current capacity [1][2][3]. Moreover, they have widespread application prospects in superconducting transmission cables, superconducting motors, superconducting generators, superconducting current limiters, superconducting magnetic energy storage and so on [4][5][6][7][8][9][10][11]. Nowadays, tapes with length of kilometers and critical current of hundreds of amperes have been prepared all over the world [12][13][14][15][16].…”

A narrow channel reaction chamber is designed in our home-made MOCVD system and applied to deposit GdYBCO films on the template of LaMnO3/epitaxial MgO/IBAD-MgO/solution deposition planarization-Y2O3-buffered Hastelloy tapes. In the reaction chamber, metal organic sources are transferred from the inlet to the outlet along the direction of the tape movement. Thus, compared to the vertical injection way of metal organic sources, the residence time of metal organic sources on the surface of substrates would be extended through adopting the novel reaction chamber. Therefore, the utilization of metal organic sources, which is calculated according to the measured results of experiments, can reach 31%. Additionally, the utilization ratio of metal organic sources based on the novel reaction chamber is basically two times as much as that of the commonly used vertical injection slit shower. What is more, through adjusting the process, the critical current density of 300 nm thick GdYBCO film prepared the reel-to-reel way has reached 3.2 MA cm−2 (77 K, 0 T).
