    dct:description "<p>The X-ray Surveyor mission concept is one of NASA&rsquo;s four large missions to be studied in the upcoming 2020 Astrophysics Decadal Review. It aims to be a true follow-on to the Chandra X-ray Observatory, retaining the exquisite &lt; 1 arcsec angular resolution in the soft x-ray band (0.3&ndash;12 keV) but with a much larger collecting area and improved instrumentation, including a non-dispersive imaging spectrometer. This combination will enable observations essential to understanding the earliest galaxies and supermassive black holes, as well as galaxy formation and the assembly of large-scale structure from the earliest epochs.</p><p>Microcalorimeters are non-dispersive devices that have achieved excellent energy resolution, providing resolving powers of&nbsp; &gt;3000 at 6 keV.&nbsp;They are the leading detector technology for high-resolution x-ray imaging spectrometers, and the X-ray Surveyor as currently envisaged includes a microcalorimeter instrument.&nbsp;But, the surveyor instrument will require a hundred times the number of pixels compared to our state-of-the-art microcalorimeter arrays: a hundred thousand pixels are needed&shy; to match the spatial resolution of the X-ray Surveyor optic while covering 5&#39;x 5&#39;. &nbsp;</p><p>This project aims to increase the technical readiness of the readout technology that is suitable for&nbsp;these large microcalorimeter arrays. In collaboration with colleagues at NIST, Boulder, we will perform readout demonstrations of transition-edge-sensor microcalorimeters using microwave SQUID multiplexer chips and newly acquired room-temperature readout electronics.&nbsp;</p>" ;
