Abstract

We discuss the implementation of a time-division SQUID multiplexing system for the instrumentation of large-format transition-edge sensors (TES) arrays. We cover design and integration issues concerning cryogenic SQUID multiplexers and amplifiers, signal management and wiring, analog interface electronics, a digital electronic feedback system, serial-data streaming and management, and system configuration and control. We present data verifying performance of the digital feedback system. System noise and bandwidth measurements for one-dimensional multiplexing scenarios demonstrate the feasibility of adapting this technology for a broad base of applications including x-ray materials analysis, imaging arrays for future x-ray astronomy missions such as Constellation-X, and submillimeter imaging arrays such as the SCUBA II instrument for the James Clerk Maxwell Telescope (JCMT).
