CCD-scale Far-IR Detector Arrays Using Code Domain Multiplexing

Metadata Updated: February 28, 2019

Large-format far-infrared arrays using, for example, superconducting transition edge sensor (TES) bolometers, have only achieved 1,000-pixel formats. Lagging behind other wavelengths due to lesser commercial/industrial technology investments, the potential for revolutionary improvement to megapixel formats has been the long term goal for far-infrared detector research for the past decade, when single-pixel detectors achieved background-limited performance for most applications.[HTML_REMOVED]The greatest challenge for producing very large (greater than 10 kpix) format far-IR detectors is in readout multiplexing. Several approaches (for TES detectors, time domain, audio frequency domain, and microwave frequency domain SQUID multiplexing) have been demonstrated in laboratory and a few ground-based experiments. However, none of these techniques has yet fielded a system with better than 40:1 multiplexing ratios. For very large arrays, this is a limiting constraint. Recently-developed Code Domain multiplexing (CDM) promises 100:1 multiplexing on a two-year timescale, with 10,000:1 multiplexing ratios over longer timescales.[HTML_REMOVED]We will demonstrate the CDM technology necessary to scale up to produce spaceworthy, far-infrared detector arrays scalable to 40,000 pixels. For this program, we are partnering with Stanford University, who will provide CDM multiplexers. We will assemble the[HTML_REMOVED]multiplexers[HTML_REMOVED]into a scalable detector test configuration to demonstrate operation and evaluate the achievable multiplex factors. The final result of this work will be to build and demonstrate a complete end-to-end CDM-based SQUID readout of a far-IR bolometer array.[HTML_REMOVED]Stanford will develop and provide the multiplexers; Goddard will purchase and assemble the electronics and software necessary to use the multiplexers; Goddard will fabricate and integrate a small TES bolometer array in a package customized for this purpose.
