Abstract
DC Superconducting quantum interference device (DC SQUID) has extensive application in the measurement of weak magnetic field, especially in nondestructive evaluation. The method has more higher sensitivity, wider bandwidth and higher space resolution comparing with traditional electromagnetic detection. The principle and application of DC SQUID measurment system are introduced.
