Batch type co-evaporation EDDC (Evaporation using Drum in Dual Chambers) system was recently manufactured to fabricate 100m - long SmBCO superconducting coated conductor. As a preliminary study before the fabrication of long tape, short CC samples have been fabricated using the EDDC system and their crystal texture and Ic properties were investigated. 1.2 ㎛-thick SmBCO layers were deposited on CeO2/YSZ/CeO2 buffered Ni-W tapes. Ic of 128A/cm-w and corresponding Jc of 1.1 MA/cm2 at 77K in self-field were obtained for SmBCO CC tape. In-field property of SmBCO CC was confirmed to be better than that of YBCO deposited by PLD.
