中文摘要	An apparatus for measuring the homogeneity of the transition temperature (Tc) and the critical current density (Jc) of large area HTSC thin films has been developed. Two step motors are used to control the movement of the scanning probe on a polar plane. There are two techniques included. The first is an ac inductive method which provides a nondestructive measurement for determining Tc. Based on the Bean model, the second technique, for detecting the uniformity of Jc, uses the surface magnetic field distribution of the material to derive the Jc profile. Measurements were carried out on a 30mm diameter YBCO sample. A Tc map and surface distribution of the trapped field after field cooling which responds to the Jc profile were obtained.
