| titleOfInvention | SQUID control device |
| abstract | (57) [Summary] (Modified) [Problem] To provide a SQUID control system for controlling multiple SQUID probes. A plurality of head units 104 corresponding to each SQUID probe are provided, and each head unit includes a non-cryogenic modulation flux loop feedback circuit that operates at a respective modulation frequency. The apparatus includes a base unit 112 coupled to all of the head units, which supply control signals to control multiple head units. Means are also provided for synchronizing all modulation frequencies of the modulated flux lock loop feedback circuit, such as by use of a daisy chain arrangement. The head unit includes a phase shifter coupled to shift the phase of the modulated frequency oscillator signal to provide a local oscillator input for the demodulator. |
