N2 - Critical current properties of a YBCO coated conductor have been studied as a function of temperature and magnetic field under high magnetic fields up to 27T. The value of critical current, Ic, for 1cm wide tape was 85A at 77K in self-field. Detailed electric field vs. current density (E-J) characteristics were measured using 100µm wide and 1mm long bridge patterned in the tape. Critical current densities, Jc, increased drastically at low temperature, e.g., Jc retained high value more than 0.4MA/cm2 in 27T at 30K. Statistic parameters of the distribution of critical current density were extracted from the E-J characteristics. Then the pinning parameters were also determined by a scaling analysis. It had been confirmed that the calculation results agree well with measurements. The errors of Jc were held less than 10% at wide range of temperature and magnetic field.
