| titleOfInvention | SQUID control device |
| abstract | (57) [Summary] A SQUID control system for controlling multiple SQUID probes (102), which is equipped with a plurality of head units (104) corresponding to each SQUID probe, and each head unit operates at each modulation frequency. It includes a non-cryogenic modulation flux loop feed back circuit. The device includes a base unit (112) coupled to all of the head units, the base unit providing control signals to control the multiple head units. Means are also provided for synchronizing all modulation frequencies of the modulation flux lock loop feedback circuit, such as by using a daisy chain arrangement. The head unit includes a phase shifter coupled to shift the phase of the modulation frequency oscillation signal in order to provide the local oscillator input of the demodulator, the phase shifter including all frequency components except the fundamental frequency component. A phase shift filter for filtering the oscillating signal and shaping means for shaping the filtered phase shifted signal into a square wave may be included to reduce the components to a desired amount. |
