【Abstract】 Non-destructive measurement system of critical temperature for large area high-T-c superconducting thin films was designed and fabricated. 13 T-c′s in 2 inch diameter thin film can be measured at the same time. During the measurement the signals can be displayed on the screen by figures or by numeral. The measurement is fast and reliable. The measurement error is in the range of 0.2K.更多还原
