SQUID Series Arrays

The SQUID series arrays are ideal for readout of TES sensors or as amplifier stage for discrete two-stage applications.

Integrated bias resistors for TES or two-stage applications reduce wiring complexity. With an input inductance of 3 nH, an input sensitivity of 23 µA/Phi0, and a current noise <10 pA/sqrt(Hz) @ 4 K these sensors cover a large range of applications.

Two independent 16-SQUID series arrays are located on one chip.

Direct mounting of the chip on a Copper block is possible as well as magnetically unshielded operation in the Earth magnetic field without degradation in noise performance.
