Simple, compact, high-resolution monochromatic x-ray source for characterization of x-ray calorimeter arrays

Eckart, M. E.; Kilbourne, C. A.; Leutenegger, M. A. +6 more

X-ray calorimeters routinely achieve very high spectral resolution, typically a few eV full width at half maximum (FWHM). Measurements of calorimeter line shapes are usually dominated by the natural linewidth of most laboratory calibration sources. This compounds the data acquisition time necessary to statistically sample the instrumental line bro…

Calibration of the microcalorimeter spectrometer on-board the Hitomi (Astro-H) observatory (invited)

de Vries, C. P.; Tsujimoto, M.; Ishisaki, Y. +21 more

The Hitomi Soft X-ray Spectrometer (SXS) was a pioneering non-dispersive imaging x-ray spectrometer with 5 eV FWHM energy resolution, consisting of an array of 36 silicon-thermistor microcalorimeters at the focus of a high-throughput soft x-ray telescope. The instrument enabled astrophysical plasma diagnostics in the 0.3-12 keV band. We introduce …
