N2 - We investigated the local inhomogeneity of flux flow dissipation by use of low temperature scanning laser microscopy (LTSLM) in a Y1Ba 2Cu3O7-δ (YBCO) coated conductor obtained by the Metal-Organic Deposition process using metal trifuluoroacetate (TFA-MOD process). The LTSLM images showed that the highest Jc value in local region reached almost two times higher than the minimum value, while the global Jc was limited by the weakest spot. Typical length scale of the spatial inhomogeneity of Jc was about several tens to hundreds μm.
