Microwave Readout to Enable the Imaging Spectrometer for the X-ray Surveyor

Metadata Updated: May 2, 2019

The X-ray Surveyor mission concept is one of NASA[HTML_REMOVED]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 [HTML_REMOVED] 1 arcsec angular resolution in the soft x-ray band (0.3[HTML_REMOVED]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.Microcalorimeters are non-dispersive devices that have achieved excellent energy resolution, providing resolving powers of[HTML_REMOVED] [HTML_REMOVED]3000 at 6 keV.[HTML_REMOVED]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.[HTML_REMOVED]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[HTML_REMOVED] to match the spatial resolution of the X-ray Surveyor optic while covering 5[HTML_REMOVED]x 5[HTML_REMOVED]. [HTML_REMOVED]This project aims to increase the technical readiness of the readout technology that is suitable for[HTML_REMOVED]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.[HTML_REMOVED]
