超导量子干涉器(RF-SQUID)是一种磁通传感器,配上适当的输入电路便可以构成高灵敏度的磁强计、磁场梯度计、磁化率计、电压表、电流计、小位移测量仪等.这些仪表有极高的灵敏度,比常规仪器高几个数量级.能解决常规仪器不能解决的许多测量问题.在低温物理、生物磁学、计量标准、地球物理等领域有独特的应用,因而具有广阔的开发前景. 我校研制的RF-SQUID为点接触双孔型器件,气密封装.它设计合理,工艺精密.整机包括三部分:探头,高频头,低频控制仪.探头顶部、底部都用超导屏蔽;器件至室温
Superconducting quantum interference (RF-SQUID) is a flux sensor, coupled with the appropriate input circuit can constitute a high sensitivity magnetometer, magnetic field gradient meter, magnetic susceptibility meter, voltmeter, ammeter, small displacement measurement Etc. These instruments have very high sensitivity, several orders of magnitude higher than conventional instruments and can solve many measurement problems that conventional instruments can not solve.It has unique applications in the field of cryogenic physics, biomagnetism, metrology standards and geophysics, Thus has a broad development prospects.Our RF-SQUID developed for the point contact dual-hole devices, hermetically sealed. It is designed, process precision. 整机 consists of three parts: probe, tuner, low frequency controller. Superconducting top and bottom shields; device to room temperature
