Abstract

The development of time-domain SQUID multiplexers enables the integration of superconducting transition-edge sensors (TES) into arrays of thousands of elements while maintaining a manageable number of readout channels. The applications for detector arrays range from high-count-rate x-ray microanalysis systems to focal plane arrays for imaging at wavelengths from the submillimeter to gamma ray. We present results from recent measurements of a two-dimensional TES array. The measurements focus specifically on the heat pulse response to a TES measured with multiplexed read-out. We describe the system architecture including the cryogenic SQUID amplifier chain, the analog interface electronics, and the digital feedback electronics.
