The design and implementation of high-temperature superconducting magnetometer control system

In this paper, a high-temperature superconducting magnetometer control system, including the operation principle and the design of hardware and software, is described and implemented. The system has the ability to automatically adjust and store the operating point of the high-temperature superconducting quantum interference device (HTS SQUID). The signal processing and output of the high-temperature superconducting magnetometer has been achieved. Utilizing the photoelectric isolation technology, the circuit noise from the control system to the magnetometer front-end circuit can be reduced. The results indicated that the designed high temperature superconducting magnetometer control system can be stabilized working in the field, and satisfies the applications of high-temperature superconducting magnetometer in geophysical magnetic prospecting.
