HTcrfSQUID用于磁异常移动测量的初步研究

摘要

高温超导量子干涉器(HTcSQUID)磁强计的基本特点是噪声低、低频响应好、工作带宽大,在需要微弱磁场测量的许多技术领域发挥着重要作用,将其用于磁异常探测(MAD)是搜索地下/水下磁性目标物的有效技术.本文采用国产射频高温超导量子干涉器(HTcrfSQUID)磁强计,在非磁屏蔽环境中开展了移动状态下的磁异常探测实验,初步结果表明,基于HTcrfSQUID磁强计的MAD技术是一项具有研究和使用价值的新技术.%HTcSQUID magnetometer is characterized by its low noise, low frequency response, and wide operating bandwidth. Behaving well in weak magnetic Meld measurement, it is often used in magnetic anomaly detection, which is an effective technology in searching underground/underwater magnetic objects. We developed a MAD experimental prototype based XY - 2 H Tc rf SQUID sensor and GXCD -2 SQUID readout/control circuit, launched a MAD test in slow moving state and non -magnetic shielding environment. The preliminary results show the use value of Hr,SQUID magnetometer in MAD.
