Abstract:We report on a superconducting quantum interference device (SQUID) system to read out large arrays of cryogenic detectors. In order to reduce the number of SQUIDs required for an array of these detectors, we used code-division multiplexing. This simplifies the electronics because of a significantly reduced number of wires from the cryogenic detectors to the SQUIDs and the room temperature electronics. Several prototype chips based on SQUIDs with multiple inputs coils have been developed and direct and indirect crosstalk properties are discussed.
